PLASTOMATIC RELIEF, BY-PASS, BACK PRESSURE & ANTI-SIPHON VALVES
ANGLE AND IN-LINE DESIGNS FOR CORROSIVE CHEMICALS, WATER AND ULTRA-PURE LIQUIDSTrue Blue ® Relief Valves provide smooth, sensitive operation to help you manage pressure "upstream" of the valve.
This valve design serves many functions:
- Preventing overpressure conditions in vessels and piping systems (relief valve).
- Providing by-pass flow relief to avoid pumping problems such as deadheading (pump bypass valve).
- Maintain backpressure in a piping system (backpressure regulator).
- Enhance pump performance by maintaining backpressure on the pump outlet (pump backpressure valve).
- Prevent gravity-induced siphoning through a pump, opening only when the pump is on (anti-siphon valve).
- NEW! Series TRVDT 3-port design...the features of our state-approved RVDT now in a 3-way valve!
And provides many outstanding features:
- Offer wide range of pressure settings with sensitive operation.
- Provide smooth operation with higher flow.
- Fail-Dry safety feature (not available on RVD or RVTX).
