LINE BLIND VALVES

As is the case with most success-ful products, the Hamer Line BlindValve was designed to meet a specificneed. With the Line Blind Valve, theneed was for a system with positive,absolute shutoff in pipelines whichcould be dependably operated by oneperson.

Since its introduction in the mid-thirties, the Hamer Line Blind Valvehas undergone a number of engi-neered improvements to meet a vari-ety of applications.

Line Blinding: An Introduction

Line blinding is the use of a solid flat plate to obtain absoluteshutoff of flow. Whether used with liquids, solids, slurries, orgases the line blinding method is unmatched in shutoff integrity.

Why LineBlinding?

Typical circumstances requiringabsolute shutoff include:

• Protection of the health and safety of personnel

• Avoidance of product contamination

• Control of products flowing through manifolds or common pipelines

It is well recognized that many con-ventional types of valves may developleaks. Causes of leaks include age,misuse, erosion and distortion. Thesevalves cannot be guaranteed to pro-vide absolute shutoff in the line.Therefore, it is necessary to close offor blind the pipeline by other means.

Line BlindingMethods

In many service conditions, theusual practice has been to blindpipelines by means of a skillet plateand gaskets inserted between twoflanges. Other common methodshave included: blanking flanges andremovable spool, block and bleedarrangements and standard valves.

Expense factors which areunavoidable in most blinding methodsinclude the time required for theblinding process, delay while the lineis shut down, loss of product causedby spillage and the hazards of fire,explosion and pollution should anydownstream leakage occur.

Why Use Hamer Line Blind Valves?Where blinding is a frequent requirement and safety is of primary concern, Hamer Line Blind Valves are essential.

• Positive, permanent shutoffWhen the blank end of the spectacle plate is clamped in position, product cannot leak to the downstream side of the line.

• Visible shutoffThe reverse end of the spectacle plate is visible outside the valve body, providing a positive visual indication of its open or closed position.

• Fast, one person operationOnly one person is needed to operate most Hamer Line Blind Valves. Blinding takes only a few minutes with an operating bar and substantially reduces operating time and cost. Other methods generally take two to four pipefitters (depending on pipe size) 30 to 45 minutes for blinding a line.

• Complete rangeThe widest range of line blind valves is available for varied applications and includes models with enclosed spec-tacle plate chambers to prevent spillage in case the line was not totally drained when the spectacle plate is reversed.

• Long service lifeExperience proves it. Hamer Line Blind Valves provide long, trouble-free service.

R&M Energy Systems offers you benefits based on the longest experience in the design and manufacture of Line Blind Valves.Product improvement and development is ongoing to meet the changing needs of the industry as well as special requirements.

This is the most commonly usedtype of line blind valve. The simple,rugged and practical design provideslong service with minimum mainte-nance requirements. The number ofbolts is determined by size and maxi-mum working pressure.

• Simple operation: Spread the line with operating bolts using only a bar or pipe. Rotate spectacle plate and tighten again in seconds, with-out special tools. (See A below).

• Compact design: Unique bolt headdesign allows installation and operation in limited space.

• Positive position indication:Visible portion of spectacle plate clearly indicates if valve is open or closed.

• Packing variation: Wide range of packings are available to suit ser-vice requirements including spiral wound stainless steel for high tem-peratures. Body packing (See B below) is standard but spectacle plate packing is optional. (See C below).

3. Tighten bolts and the line blind valve is secure in open or closed position.2. Rotate spectacle plate.1. Loosen three bolts.

Plate PackingRugged, plate-retained packing rings

provide wide sealing area, long life andquick seal replacement.

Body PackingRugged, body-retained packing rings

are protected from exposure andprovide wide sealing area and

long life.

Bolt LubricationBolts are phosphate treated to prevent

seizing. In addition, lubricant channel isprovided by grease zerks fitted to bolt end

to assure smooth operation.

• Full flow: Minimal turbulence occurs through full round port and pressure drop is negligible.

• Minimum maintenance: High quality alloy nuts and bolts have through bolt-to-nut lubrication feature (See D below). Spectacle plate is plated for corrosion resis-tance on carbon steel blinds.

• End connections: Available with butt weld or flanged ends with optional B16.10 end-to-end dimensions.

• Time saving: Operate only a fewbolts, instead of loosening and tightening 4 to 12 bolts on a stan-dard flange. Reversing the plate usually takes less than a minute.

• Safety: Absolute assur-ance of no downstream leakage. Alignment-locking pin is standard.

• Wedge action: provides positive, absolute closure.

• Full flow when open: Open wedge provides unrestricted flow.

• Easy operation: Handwheel allows quick operation.

Wedge-shaped discs are used in this type of Line Blind Valve.Suitable applications include any hori-zontal piping installation where linespread is not possible, and wherefluid loss is not acceptable. Sinceoperation of this type of valve is by ahandwheel, even larger size valves areopened and closed quickly and easilyby one person, without tools.

Cement IndustryThe picture to the left shows a

typical manifold of 10" Hamer Sliding Gate Line Blind Valves. Themanifold is located at the top of a siloand is used to effectively segregatedifferent types of cement, therebyavoiding any possibility of productcontamination. In this photo, thevalves are shown in the closed posi-tion. They are operated pneumatical-ly by plant air, usually between 60and 80 psi. In order to ensure easeof operation in the abrasive environ-ment of cement service, each gate isthoroughly molycoated.

Steel IndustryHamer meets the need for safety

with absolute shutoff of coke ovengas and blast furnace fuel lines withthe specially designed 5-bolt LineBlind Valve. These valves are availablein sizes 16" and larger, with larger sizesequipped with a counter balance forease of operation.

Marine IndustryWith Hamer Line Blind Valves,

dependable product isolation onbarges or tankers is assured. Byusing the Line Blind Valve, contami-nation due to an inadvertently openvalve is virtually eliminated.Additionally, the absolute shutoffachieved by the Hamer Line BlindValve protects both product and personnel from problems related to leakage. The visible wedge modelis extremely well suited for applica-tions in rigid piping aboard shipswhere spillage control is essential.
