Structural Features

- Valve BodyValve body is an integral casting piece which has adequate rigidity against external force in pipeline. It is full port, circle shape and through conduit, this makes small loss of pressure and pipe pigging feasible.

- SeatFloating seat rings & gate enable automatic sealing by pressure and double block of upstream & downstream valve seat.Soft-seated design ensures “bubble tightness” sealing and self-cleaning.Floating seat rings always conta ct gate closely, sealing faces are well protected so that to prolong its service life.

- Overpressure Release of Valve CavityThe overpressure of valve cavity is released automatically to upstream through seat ring, thus relief device of overpressure in body cavity is not required. When valve is fully closed, the upstream and downstream pressure will be blocked by valve seats, and then valve can be vented or drained.

- GateThe gate i s des ign with divers ion hole, it is always consistent with seal surface either is fully open or fully closed, the seal surface is protected from fluid erosion so as to prolong the valve service life.

- StemThere is no side load against stem, which results in low operation thrust. The stem is furnished with a protective enclosure and visible opening indicator. Stem sealing system consists of stem packing and back seat, packing gland is adjustable online.

- Stem EnclosureStem enclos ure is a protective device of stem, it can prevent stem thread from external damage, thus to prolong its service life. Stem indicator can indicate the opening status of the valve so that to avoid error operation.

- Limit of TravelThe fully open or close status of valve is reached by travel limit rather than operating torque

- Mounting Pad( A d a p t e r F l a n g e ) T h e mount ing pad compl ied with ISO 5211 is suitable for various actuators. Actuator can be coupled with valve at fact ory or in the field.

- Sealant Injection Port of StemIn normal condition, stem sealing is not achieved with sealing grease. Sealing grease can be injected through injection port for urgent repair in the event that stem sealing is failed due to one or another reason.

- Drain PortDrain fitting is installed on the bottom of valve body, valve can be vented or drained through drain fitting. The drain fitting can be an insulation valve or a special plug, safe and convenient.

- The design and manufacture conform to A PI6D/ISO14313

- Sealant InjectionIn normal cond i t ion , s tem sealing is not achieved with sealing grease. Sealing grease c a n b e i n j e c t e d t h r o u g h injection port for urgent repair in the event that stem sealing is failed due to one or another reason.Each sealant injection port is installed an injection valve and a buried non-return valve. The typical injection valve has a helmet to secure its safety and reliability. There is a buckle d e s i g n e d a t t h e h e a d o f i n j e c t i o n v a l v e f o r f a s t connection of injection gun.

Structural Features-

Principle of WorkW hen the internal pressure P1 is equal to P2, the gate is in

closed status, the soft seat performs initial sealing. Every time when the valve is opening or closing, the soft seat can clean the side faces of the gate

When the upstream pressure P1 exceeds downstream pressure P2, the pressure is acting at the gate and pushes it toward the downstream soft seat until it tightly contacts the metal seat ring, so that to make double sealing of soft-to-metal and metal-to-metal.

After that, the medium push the upstream seat against the gate to achieve double block of upstream & downstream.

When pressure P3 in body cavity exceeds pipeline pressure, the pressure P3 will push the seat rings away from gate so as to release the exceeding pressure into pipeline. When P1 exceeds P2, the pressure in body cavity will be released to the side of P1; When P1 is equal to P2, the pressure in body cavity will be released to both sides.

There are two different designs of Seat-to-G ate sealing: Traditional Soft Seal: the inserted soft seal is the seal of

polymer to the gate, it is feasible for low pressure ratings.ZAF Combined Seal: The soft seat insert made of special elastic

material acts as major seal to ensure zero leakage required by API 6D. An additional RPTFE seat is designed beside the major seal to provide protection, so that to prolong the service life of the major seal. This kind of design features a metal to metal “quasi-seal” between seat and gate.

Val ve Ends The valve ends can be made as per clients' requirements, the normal ends includes flange, butt welding, clamps or any of two.

Face to Face DimensionFace to Face dimension conforms to API 6D. However, Face to Face dimension beyond API 6D will be according to the manufacturer's standard or defined by the client.

Vent or Drain

- Double Block & Bleed (DBB)When the gate is fully open or closed, the fluid in the valve cavity can be vented or drained, at this moment both seats are shut off, either entry of the valve can work at full DP. DBB function enables the operator to bleed the valve cavity online and to check the seating integrity.

Surface Treatment of TrimThe gate, seat and stem can be electroless Nickel plated (ENP) as per client's request. ENP strict manfacture ensures the perfect surface hardness & anti-corrosion performance of the metal, and dramatically improves its resistance against erosion & corrosion, minimize its friction coefficient.In addition, if required by service condition, anti-corrosion materials or hard facin g with alloy for critical sealing parts are available.

Advanced EquipmentsAdvanced equipments are necessary for high-performance slab gate valve. All the essential spots of ZAF slab gate valve are machined by CNC lathes & grinder, so that to guarantee the 100% primary qualified rate and 100% inter changeability of the products.

Flow Character istics

Characteristics of Equal Percent. For slab gate valve without diversion hole, its cavity shape is relatively regular and the cavity span is smaller than wedge gate valve, therefore, except its pressure loss is bigger, basically other characteristics are similar with slab gate valve with diversion hole.For regulating type slab gate valve with diversion hole, its regulating function is superior to the flat gate valve without diversion valve.

- Brief DescriptionZAF light slab gate valve is suitable for installation near storage tank or at high altitude. The fully welded body and bonnet results in light weight, the most optimum design is achieved by finite element analysis. It is of the basic features of the ordinary full opening slab gate valve, but its weight is only one-third of the latter. This unique design can reduce the loads of pipeline, and consequently prevents pipeline from sinking, meanwhileminimizes the adverse influence of foundation changes against pipeline and fa cilities

Brief DescriptionThe K-type expanding slab gate valve is a kind of high performance gate valve with outstanding features. This type of valves possesses functions of double & bi-directional sealing and reinforced mechanical sealing. it is full bore and feasible for pipe pigging, is widely used in pipelines of subterranean heat steam, petroleum, natural gas production, transmission, collection and storage. It is also suitable for corrosive f luids like coal gas, acid, alkali and etc. .

FeaturesFull bore suitable for pipeline pigging, smooth path, small flow resistance and no pressure loss.No matter the valve is fully open or fully closed, the fluid is insolated from valve cavity, this feature allows the

operator to release the pressure through vent & drain fittings in emergency situation, and then solve the accident in safety.

The unique top-entry design enables professional maintenance personnel to change the intern al parts of the valve online.

Due to bi-directional sealing design, the pressure entrapped in valve cavity cannot be released to downstream through downstream seat; the pressure may rise because of temperature change or other reasons. In this case, the pressure in valve cavity can be released by a safety device in valve body so that to assure the safe running of pipeline and facilities.

The installation location of this kind of valve is diverse, it can be vertical, horizontal, backward or slanting.Stem packing material can be replaced safely online.The fully-enclosed structure has perfect protection property and it is all-weather suitable.Working Principle

Open Position

When the valve is fully open, the upper back angles are separated f rom each o ther and gate-segment assembly s tar ts to expand, sealing against both seats, insolating valve cavity from flow fluids and foreign

During Open/Close Travel

During open/close travel, the upper & lower back angles are in contact with each other, the tiny space between gate-segment assembly and seats a l lows the gate-segment

Closed Position

When the valve is fully closed, the lower back angles are separated from each other and the gate-s e g m e n t a s s e m b l y s t a r t s t o expand, pressing closely against both seats and forming a tight

Moved by actuating device, the stem drives the gate up and down and the segment i s m a k i n g a s i m u l t a n e o u s movement by a connecting rod, thus to achieve the passage or s h u t - o f f o f t h e f l u i d b y mechanically expanding the gate-segment assembly.
