DQR / DIRECT ACTING RELIEF CONTROL VALVE
PRODUCT DESCRIPTION
The direct acting relief control valves like the pressure relief control valves are used for evacuating excessive pressure. The direct acting relief control valves’ opening up speed is higher compared to the other relief valves bacause the pilot valve is not effective.
PROPERTIES
1- Protects piping system and other armatures through discharging excessive pressure which may occur within the valve network to atmosphere quickly.
2- Valve opens quickly, and then, after the discharge is completed, it is closed slowly and with a full-sealing, without causing any pressure fluctuation again in the line.
3- Operates hydraulically, completely with line pressure, without requiring an extra power supply.
4- Owing to its design with diaphragm actuator, its maintenance is considerably easy and cheap.
5- Operates safely, even in horizontal and vertical installations.
