Pressure Relief Valves from Flow-Tek are engineered to deliver high-performance pressure control, ensuring safe, reliable operation in industrial water, oil, and gas systems. Flow-Tek Pressure Relief/Sustaining Valves are diaphragm-actuated control valves designed to perform two critical functions effi.iently and dependably.
When installed in-line, these valves maintain a consistent minimum upstream (back) pressure, keeping systems stable even under fluctuating flow or changing downstream conditions. When configured as circulation valves, they automatically release excess pressure above the maximum preset, providing safe, controlled, and efficient operation across the system.
Features
- Prioritizes and maintains designated pressure zones within pipeline networks
- Ensures controlled and gradual pipeline filling to prevent surge damage
- Prevents unintended pipeline emptying and backflow conditions
- Protects pumps from overload and cavitation during operation
- Maintains minimum required pump flow for safe performance
- Provides protection against excessive line pressure buildup
Applications
Pressure Relief Valve is a hydraulically operated, pilot-controlled, modulating valve engineered to maintain precise upstream pressure within narrow limits. It performs multiple roles including pressure relief, pressure sustaining, backpressure regulation, and system unloading in bypass configurations, ensuring safe and stable pipeline operation.
