• Shipped with Relief Valve and Bypass Drain Ports Plugged to Expedite Pressure Testing
• Locking Kit Available
Repair kits are available for all TEST an
DRaIn ® valves. Kit includes: Adapter Gasket (1), Ball (1), Valve Seats (2),
Stem Packing (1), and Stem Washer (1). Valve and orifice size must be specified when ordering.
Note: It is important to note that the pressure rating of the relief valve indicates an operating range of pressure for both opening and closing of the valve.
Standard relief valves are required to oPeN in a range of pressure between 90% and 105% of their rating. the valves are required to CLoSe at a pressure above 80% of that rating. the relief valve should be installed where it is easily accessible for maintenance. Care should be taken that the relief valve CANNot be isolated from the system when the system is operational. A relief valve should NeVeR have a shutoff valve or a plug downstream of its outlet.
