Applications
1.The valve is a 2/2-way pneumatically actuated piston valve for liquids, gases,
steam and some aggressive fluids (vacuum services also.).
2.The superior design of the piston is unique to the market, enabling the plug to
retract farther from the flow path, ensuring the highest flow capacity.
3.Widely applied on air drying equipment, sterilizers, autoclaves, pollution
control equipment, process control applications, laundry equipment, textile
dyeing & drying, bottling & dispensing equipment, industrial compressors.
Features
1.Spring return normally closed, single acting.
2.Easy to install, infinitely rotable actuator allows pneumatic connection in any position.
3.With pilot air pressure, zero leakage.
4.Maintenance-free actuator with long-life piston ring and high reliability.
5.50% higher flow rate than globe valves.
6.Many types of connection, such as screw thread, flange, welding.
7.With water hammer-free function
