Model Floor 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
• Designed for easy maintenance, the grate can be accessed simply by removing the lid and reaching in. No tools are required.
• 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.
• Integral Cast Water Stop
• Because our water stop is integrated into the cast valve, we can help prevent water from leaking around 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.
