The ZPL270F Spherical-Housing Shutoff Globe Control Valve is a high-performance linear motion fluid control valve.It features a normally closed pneumatic design with a single-acting spring-return cylinder in a high-in/low-out configuration,combining the functions of a check valve and safety valve.
The cylinder is equipped with a high-temperature fusible plug that provides automatic pressure relief and shut-off functionality in case of excessive temperature.During operation:Valve Opening:Air pressure acts on the cylinder,pushing the piston upward against the spring force.Valve Closing:When air supply is cut off,the spring force and medium pressure from the storage tank drive the piston downward.
With its excellent sealing performance and rapid shut-off characteristics,this valve serves as a critical device for industrial fluid control,providing reliable safety protection and operational efficiency for industrial processes.This Valve with the key features as:Linear stroke operation,Available in soft-seal or metal-seal versions,Fusible plug safety feature,Combines check valve and safety valve functions & Fast response time.
This valve plays a crucial role in industrial applications,idea for critical shut-off applications in:Petrochemical plants,Gas distribution systems,Industrial process control,Safety protection systems,etc.
