  • How to Select a Pressure Relief Valve
    Don't make the mistake of trying to pick the right relief valve for your application based on just the size of the pipe in the system or the set pressure. Do it this way and you are almost guaranteed to be spending time trying to figure out why the valve is not doing what it is supposed to do.
  • Product Development Process: Positive Pressure Relief Valve
    Readily available pressure relief valves did not meet NASA's stringent requirements for space flight and thus another approach was desired.
  • Learn About Temperature and Pressure (T&P) Relief Valves
    Learn more about the role of residential temperature and pressure relief valves and the causes of T&P valve discharge.
  • Natural Gas Fractionation Process Facilities Rely on Flow Switch for Relief Valve Leak Monitoring
    A company with multiple natural gas liquid (NGL). fractionation process facilities located in the. Southeastern U.S became concerned about a series of. missed events and nuisance alarms caused by the flow switches installed to monitor potential overpressure situations with its pressure relief

    and a pressure-relief valve. Clamped to the base with a large O-ring, the chamber has two quick-disconnect fittings for filling and purging. The chamber is made of low-outgassing transparent molded poly- urethane which blocks UV light at a rate of 2% below 250 nm. The filter in the nitrogen input line is rated
  • Sizing up flow forces
    a nonpressurecompensated pump, relief valve, and a two-way, two-position solenoid spool valve. Theoretical results for a flow of 10 gpm and relief pressure of 3,000 psi are presented as the 0-m-n line. Test results for pilot-operated and direct-acting valves are also shown, indicating a good correlation between

    A high-flow 3-in. NPT relief valve for corrosive and ultrapure liquids also serves as a back-pressure regulator and bypass valve. The Series RVTX angle-pattern valve is made of Grade 1, Type 1 PVC and comes with a choice of Viton or EPDM elastomeric seal. It can be customized or made of other
  • Intensifiers
    of time without using power or generating heat in the circuit. They deliver fluid only when the cylinder demands it. Since all the oil from the booster is directed to the cylinder, there are no relief-valve losses. Generally, boosters can be used as a hydraulic power source only in single-cylinder
  • A hydraulically powered bike
    to 12,500 rpm and maximum operating pressure of 320 bar. Modifications to the standard products include cast-aluminum casings that reduce weight from 2.5 to 1.4 kg. A relief valve in the pump safeguards against excessive hydraulic pressure should the rear wheel lose all grip and spin excessively
