Pressure Relief Valve for Wastewater Wastewater Speciality Valves

Description

A pressure relief valve is a safety device that is designed for protecting a pressurized vessel or system during an overpressure event. An overpressure event is a condition which would cause pressure in a vessel or system to increase beyond the specified design pressure or maximum allowable working pressure. The primary function of a pressure Relief Valve is the protection of life and property by venting fluid from an overpressurized vessel. Several electronic, pneumatic and hydraulic systems exist today to control fluid system variables like pressure, temperature, and flow. Each of these systems requires a power source of some type such as electricity or compressed air in order to operate. A pressure relief valve should be capable of operating at all times, especially during a period of power failure when system controls are non-functional. The sole source of power for the pressure Relief Valve, therefore, is the process fluid. The pressure Relief Valve may be the only device remaining to prevent a catastrophic failure, once a condition occurs that causes the pressure in the system or vessel to increase to a dangerous level. Since reliability is directly related to the complexity of the device, it is important that the design of the Pressure Relief Valve be as simple as possible. The pressure Relief valve should open at a predetermined set pressure, flow a rated capacity at a specified overpressure, and close when the system pressure has returned to a safe level. The design of Pressure Relief Valve must be made with materials that are compatible with many process fluids from simple air and water to the most corrosive media. They should also be designed to operate in a consistently smooth and stable manner on a variety of fluids and fluid phases.

We supply 106-RPS and 206-RPS pressure relief valves which are based on the 106-PG and 206-PG main valves. The pilot senses the upstream pressure through a connection to the valve inlet. The valve and pilot remain closed until the pilot setting is exceeded by the inlet pressure. The valve opens rapidly to relieve damaging overpressure and closes smoothly at an adjustable speed when the pressure returns below the set-point. The upstream pressure is limited to the pilot set point. As a trusted supplier of several wastewater valves and other products, we can always help you with the best products at the best prices.
