Wholesale Industrial DRV valve china Static Balancing Valve China factory supplier Manufacturer
What is DRV valve ?
DRV valve ， Static Balancing Valve also known as balancing valves, manual balancing valves, digital lock balancing valves, double-position regulating valves, are used to solve the problem of branch pressure differential balance in pipeline design ball.
DRV valve ， Static Balancing Valve make it possible to introduce appropriate pressure drops so that each branch of the hydraulic circuit has the required design flow rate.
Main features of DRV valve
Main features and Benifits of NORTECH DRV valve Static Balancing Valve
- *These are Y-Pattern globe valves supplied with two pressure test points P84 to provide flow measurement, regulation and isolation
- *The Double Regulating feature allows the valve to be used for isolation and to be reopened to its pre-set position to maintain required flow rate
- *Numerical indicator of opening rate on the handwheel
- *Accuracy of flow measurement is ±10% at the full open position of the valve
- *Using balanced valve core, easy to adjust
- * Self-sealing measuring points to protect against leakage
- *Some reduction in accuracy occurs at partial openings of the valve in accordance with BS 7350
Specifications of DRV valve
