High Bank Low Bank Medium Bank Low Bank Medium Bank High Bank Rotary Actuator + Ball Valve Pressure Regulator Relief Valve Mains Supply MV MV MV PT RV RV RV RV RV RV RV PT PT MV MV MV MV MV MV RV RV Kompressor Problems associated with this system are: > Gas or air is vented to atmosphere on every filling cycle > Complex pipe work system with a large number of high pressure fittings > Costly and time consuming to install and maintain > High number of potential leak paths Exhaust to Atmosphere Relief Valve Pressure Regulator Compressor Medium Bank High Bank Low Bank High Bank Medium Bank Low Bank Rotary Actuator + Ball Valve IMI Precision Engineering Solution Each CNG line previously consisting of ball valve, rotary actuator and pilot solenoid is replaced by a solenoid valve manifold with integrated check valves and filters. Benefits > Great increase in the system reliability > Reduction in installation cost > Simplified servicing > Zero wasted Gas vented to atmosphere > No requirement for a compressed air infrastructure > High reduction in component count and fittings > Reduction in potential leak paths Manifold solution B Manifold solution A Two Hose Dispenser MV = Solenoid Valve RV = Non Return Valve PT = Pressure Transmitter 6 ENERGY CNG manifold solutions With 75 years' experience manufacturing sophisticated solenoid valves, we are confident in the reliability and performance of our products, and we are now providing valued added solutions by incorporating our proven valve technology into customized valve manifolds. Typical priority panel three bank system using; ball valves, rotary actuators and pilot solenoid valves Typical systems used in priority panels and dispensers utilize the CNG to drive rotary actuators, which in turn open and close ball valves. Alternatively, a compressed air infrastructure is installed, and compressed air is used to drive the rotary actuator.
