best 240LPM pilot check valve


Butterfly valves offer a rotary stem movement of 90 degrees or less in a compact design. unlike ball valves, butterfly valves do not have pockets in which fluids and gas may become trapped when the valve is closed. globe valves are linear motion valves with rounded bodies, from which their name is derived. they are widely used in industry to ...
If you have a pilot operated check valve with a 3:1 ratio pilot piston, then you would need a pilot pressure at port 1 that is 1/3 of the pressure being checked at port 3 plus the spring. for example, if you had 3000 psi on port 3 and a 5 psi spring and a 3:1 pilot ratio, it would take 1002 psi [(3000 psi + 5 psi) / 3)] to release the check valve.
Series asp is a speed controller with an integrated pilot check valve. this combination makes it possible to control cylinder speeds and permits temporary intermediate stops. the asp is standard with electroless nickel plating on all brass parts and allows 360 degree freedom for tube mounting direction.
Pilot line will fall, causing the valve to restrict the flow exiting the actuator and preventing load runaway. in the following pages, we will take a look at various tasks that can be performed by counterbalance valves, specific applications in which different valve types may be used, and the types of valves best suited to each task.
