1 VPS Series Static Balancing Valve

2 VPS Static Balancing Valve The Static Balancing Valve is also called double regulating valve. Primarily used in injection or other circuits requiring a double regulating valve for systems balancing. The Static Balancing Valve offers an accuracy of ±5% for precise flow regulation. The valve is designed in accordance with BS 750. VPS Static Balancing Valve, DN-0 Specification Y-pattern valves having characterized throttling disk tend towards equal percentage performance, fitted with Integral square edged entrance orifice plate and insertion test points. Double regulating feature allows valve to be set with an Allen key. Operation of the valve is by means of the Microset hand wheel. All valves operate from close to fully open with complete turns of the handwheel. The digit in the outer window indicates tenths of a turn.

3 VPS Static Balancing Valve, DN-00 Specification Y-pattern valves having an integral orifice plate tend towards equal percentage performance. The 'Microset' handwheel indicates the final valve setting. The relationship between pressure drop and flow is not altered by the handwheel setting. DN-0 valves operate from close to fully open with complete turns of the handwheel, turns for DN00/DN0 and turns for DN00. The digit in the outer tenths of a turn.
