Model Wall Type -Pressure Relief Valves

Machined Seat

Our strong, flat surface lid with resilient to bronze seating outperforms typical rubber to rubber seals, which are very wide and difficult to seal properly.

Removable Grate in Wall Pipe

Designed for easy maintenance, the grate can be accessed simply by opening the lid and reaching in. No tools are required!

Wall Pipe Extendable with PVC

With the ability to extend to match exact wall thickness, our valve eliminates the need for extra field work.

Rubber Gasket Bonded to Lid

Our gasket won`t collapse under water pressure because it is bonded to the lid and reinforced by a stainless steel washer.

Integral Cast Water Stop

Because our water stop is cast into the wall pipe, we can help prevent water from leaking around the outside of the wall pipe.

Stainless Steel Hardware

All hardware on the valve is made of stainless steel so it won’t corrode and bind up the valve.

Maintenance

The valve requires no lubrication. There is no requirement for regular maintenance. Valve seats should be visually inspected for damage when the valve is accessible.

Installation

Valves are to be mounted vertically only. Care should be taken to prevent damage to the seats when placing in form and pouring concrete. Cover and grate should be installed in the body, turned a quarter turn, and tested to be sure cover and grate cannot lift off body.
