What pneumatic quick cut-off valve and pneumatic adjustment cut-off valve?

Pneumatic quick-closing valve is driven by double-acting cylinder, which has large opening and closing torque, fast action speed, rapid opening and closing of the valve and small flow resistance loss.

The working principle of pneumatic regulating cut-off valve is that compressed air is the power source, the cylinder is the actuator, the valve is driven by electric valve positioner, converter, solenoid valve, position keeping valve and other accessories to realize on-off or proportional adjustment, and the control signal of industrial automation control system is received to complete the adjustment of various process parameters such as flow, pressure and temperature of pipeline medium.

The difference between the two is that the former is either fully open or fully closed, and the latter is mostly used for protection.

The latter can be switched at any position, and the flow or pressure can be adjusted.
