An example of a normally-closed actuated valve is Plast-O-Matic's Series EASMT Solenoid Valve. The valve opens when energized, and when that current is turned off, an isolated spring inside the valve forces it closed. The magnetic force of the solenoid coil must overcome the force of the ...
In the unpressurized condition, the valve seat is closed. A 3-way solenoid valve, which can be mounted on the actuator, controls the independent pilot medium. When the solenoid valve is energized, the piston is raised against the action of the spring and the valve opens. A normally-open ...

Gas Safety Shut-off Valve-The Gas Safety Shut-off Valve is used to cut off the source of upstream dangerous materials in the event of equipment failure, corrosion damage, seal failure, leakage, or emergency, to avoid the expansion of the accident scope,
There are two types: normally closed and normally open. When the electricity is turned off, the normally closed type closes. The movable iron core overcomes the spring force and attracts the static iron core to directly open the valve when the coil is energized, and the medium is in ...

The flow control valves are used for controlling and adjusting the fluid or gas flow through the system. The pressure control valve is used to regulate the pressure of a fluid passing through the pipe.
Pneumatic angle seat valve function: Keeping the flow rate saves space. It uses a single-acting pneumatic actuator with spring-safe safety to operate the directional angle seat valve. • Use normally open or normally closed. Working principle of pneumatic angle seat valve: ...
