06 CNG Valve Technolog
CNG Manifold Solutions With over 80 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. Exhaust to Atmosphere
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. Manifold
Problems associated with this system are: V1 » Gas or air is vented to atmosphere on every filling cycle High Bank » Complex pipe work system with a large number of high pressure fittings V2 » Costly and time consuming to install and maintain Medium Bank
