20” INSPECTION MANHOLE

• EASILY INSTALLED

• LOW MAINTENANCE

• ECONOMICAL

• LARGE OPENING

Tiona Inspection Manholes provide quick, safe entrance and exit from your tanks. Heavy gauge metal and welded construction minimizes maintenance. Manholes are certified and marked in accordance with 49CFR178.345-5 with a test pressure of 36 psi [2.48 bar].

* Add letters to part number to designate seal material. See

material table at right for designation. “X” in assembly number designates manhole collar sold separately. Collars are available in aluminum, steel and stainless steel. Please see parts page for part numbers. During installation and welding to the tank, care should be exercised to insure collars remain flat and round. If necessary, a welding fixture should be used to prevent distortion.

MAINTENANCE: Manhole assemblies should be inspected with sufficient frequency and due regard to the products carried to insure a liquid tight closure. Any worn, damaged or missing parts must be replaced. Gaskets should be replaced if their effectiveness is impaired in any way. Replacement gaskets must be compatible with products carried. Adjustment due to gasket wear may be necessary to insure proper sealing of the 10” fill. A shim washer, item No. 4, is provided for this purpose. To increase the sealing force of the 10” fill, remove shim from location shown above and re-position it above fill cover No. 1.

With Pressure Relief Valve

PAF Manholes with Model PAF450 10” Pressure Relief Valve are certified for use on MC306 cargo tanks. Manholes are certified and marked in accordance with 49CFR178.345-5 with test pressure of 36 psig. Per 49CFR180.405(h)(3), PAF450 assemblies may not be installed on MC306 cargo tanks after August 31, 1998. However, relief valves installed on MC306 cargo tanks on or before August 31, 1998, may be repaired if required. PAF450 relief valves may be installed on non-specification tanks or in tanks built in countries other than the United States where regulations permit. Relief valve also serves as a 10” latch style fill which can be easily opened for filling the tank or for inspection. Standard features include heavy duty clamp ring, secondary safety latch and model 6238AL Normal Vent. *No provision has been made for venting of product due to overfilling. Manholes are also available with a self-latching feature which allows the Pressure Relief Valve cover to open only 91 degrees and drop closed and securely latch upon movement of the tank if the cover is inadvertently left open. For self-latching model substitute 9763 for 9720 in assembly number.

NOTE: Manhole assemblies, as listed above, have Viton gaskets (suffix “V”). For other gaskets available, see parts page for correct suffix. During installation and welding the collars to the tank, care should be exercised to insure collars remain flat and round in order to assure proper performance. If necessary, a weld fixture should be used to prevent distortion.

With 10” Fill

Hot Product Manholes are designed for use on tanks hauling elevated temperature materials and are rated with a 25 PSIG yield pressure to meet the requirements of 49CFR 173.247(g)(2), which states:

“…Closures must be designed and constructed to withstand, without exceeding the yield strength of

the packaging, twice the static loading produced by the lading in any packaging orientation and at all

operating temperatures.” Hot Product Manholes are designed to retrofit existing PAF Manholes on elevated temperature tanks in order to bring them into compliance with the current closure requirements, as well as for new construction tanks. The design features a 10” fill to provide tank access for filling or inspection and a heavy duty clamp ring which can be removed to provide access into the tank. Steel assemblies are black epoxy coated for corrosion resistance.

With Integral Relief Valve/10” Fill

PAF manholes with integral latch style surge suppression relief valves are designed for use on DOT406 and replacement on MC306 specification cargo tanks. Manholes are certified and marked in accordance with 49CFR178.345-5 with a test pressure of 36 psig. Manhole covers are 7 gage steel or stainless and are secured to the tank weld collar with a clamp ring and bolt which can be easily removed to provide access into the tank. The integral 10” relief valve provides emergency pressure relief and meets the 1 liter surge leakage limit imposed by 49CFR178.345-10(b)(3)(ii). The relief valve also serves as a 10” latch style fill which can be easily opened to provide access for filling the tank or for inspection. Relief valves contain an adjustment feature to allow for fine-tuning of set pressure in the field. Other standard features include a heavy duty clamp ring, secondary safety latch and model 6496ALB pressure-vacuum vent mounted in the 10” relief valve cover. Manholes are available with a self-latching feature that allows the 10” relief valve/fill cover to drop and securely latch upon movement of the tank if the cover is inadvertently left open. For self-latching model substitute L720 for L763 in assembly number.

PAF manholes with integral latch style surge suppression relief valves are designed for use on DOT406 and replacement on MC306 specification cargo tanks. Manholes are certified and marked in accordance with 49CFR178.345-5 with a test pressure of 36 psig. Manhole covers are 7 gage steel or stainless and are secured to the tank weld collar with a clamp ring and bolt which can be easily removed to provide access into the tank. The integral 10” relief valve provides emergency pressure relief and meets the 1 liter surge leakage limit imposed by 49CFR178.345-10(b)(3)(ii). The relief valve also serves as a 10” latch style fill which can be easily opened to provide access for filling the tank or for inspection. Relief valves contain an adjustment feature to allow for fine-tuning of set pressure in the field. Other standard features include a heavy duty clamp ring, secondary safety latch and model 6496ALB pressure-vacuum vent mounted in the 10” relief valve cover. Manholes are available with a self-latching feature that allows the 10” relief valve/fill cover to drop and securely latch upon movement of the tank if the cover is inadvertently left open. For self-latching model substitute L863 for L820 in assembly number.
