Pneumatic Knife Gate Valve

Middleeast Valve is a well known supplier of  Pneumatic knife gate valve in Saudi Arabia. Which supplies valves to different industries around the world.

Pneumatic Knife gate valves are linear shut-off valves with a compact design and minimal weight. Valves can be operated manually with a handwheel or automatically with a pneumatic cylinder actuator. Our knife gate valves are perfect for many applications in the process industries of pulp and paper, wastewater treatment, mining, sugar mills, and chemical processing because the arc shape of the gate is specifically designed to be suitable for cutting off fluid containing fibre or suspended particles.

Pneumatic actuator

A pneumatic actuator is a device that transforms gas or compressed air into mechanical motion. It is sometimes referred to as air cylinders, pneumatic cylinders, and air actuators.

It is used as an automated control to reduce the amount of time that humans are required to interact with a system’s internal workings. This is particularly beneficial for automatic modulation and emergency shutdowns.

Knife gate valve

A knife gate valve closes completely against a soft sealing barrier by elevating a plate with a planar or “knife” edge out of the flow passage. This edge can physically cut through various obstructions during closing. This supple sealing surface is often only appropriate for use in relatively low-pressure systems because it was not made to withstand high pressure. Rather than a throttled or partial-flow use, gate and knife gate valves are primarily designed for isolation or on/off service.
