· be used for safety valve sizing purposes where they are required. Description The DRV7 is an SG iron direct acting bellows sealed pressure reducing valve. The standard version has an EPDM diaphragm and is suitable for steam, water and air applications. The DRV7 is available with a Nitrile rubber diaphragm (suffix 'N') for oil applications.
The Rexroth DRV flow control valve has the following characteristics 1. Simple structure, easy to manufacture and maintenance, and low cost. 2. Regulation accuracy is not high, and can not be adjusted in a wild range. 3. The sealing surface is easily eroded. 4. Poor sealing capacity.
· DOUBLE REGULATING VALVE Double Regulating Valve (DRV) Features & Benefits • The Double Regulating Valve offers an accuracy of ± 5% on all settings for precise flow regulation • Y-Pattern globe valves with characterised throttling disc tending towards equal percentage performance.
· DRV is a flow control valve in the same design which also allows the same fine flow adjustment, but in one direction only. Unrestricted flow in the reverse direction is via the built-in check valve (cracking pressure 0.5 bar). Up to 180 l/min Up to 350 bar FUNCTION DRV
· commissioning stations (FODRV) and double regulating valves (DRV). Each valve is capable of being set in any one of 100 positions each clearly defined. This ensures easy and accurate flow rate settings even after the application of thermal insulation. To set the regulating spindle an allen key (not supplied) is inserted through the spindle.
