Pneumatic Valves (Actuated Shut-Off Valves)

Pneumatic valve (actuated valve) is a valve with a pneumatic drive mechanism, which uses a diaphragm or pneumatic piston inside.

Specialist Pneumatic Valves

Our domestic company "Specialist" offers pneumatic valves with single and double-sided control, with straight or angled seat, with bronze or stainless steel body, seals NBR, Viton, PTFE or POM, covering the tasks of valve control for liquids with different compositions.

Angled Valves with Single Pneumatic Actuator (with spring return) SV-HS

The feature of SV-HS valves is the arrangement of the actuator and seat at an angle to the pipeline. This design ensures a straight flow path in the open state, without large bends that would create obstacles — allowing for a high flow capacity with relatively compact size. A second advantage is high tightness.

You can pick up pneumatic valves from the warehouse in Lviv or Kamianske in Dnipropetrovsk region, or order delivery by Nova Poshta to Kyiv, Bila Tserkva, Vinnytsia, Rivne, Ivano-Frankivsk, Lutsk, Zhytomyr, Cherkasy, Chernihiv, Dnipro, Mykolaiv, Kherson, Sumy, Poltava, Kryvyi Rih, Zaporizhzhia, Kharkiv and other Ukrainian localities under Ukraine's control.

Operating Principle of Pneumatic Actuated Shut-Off Valve

Shut-off valves of the seat type have a movable plunger as a sealing element, which in the closed state enters a "seat" — a support surface that repeats the cylindrical or conical shape of the plunger head.

The valve actuator can be either a diaphragm or a pneumatic piston with a movable plunger fixed to it. A piston type in a plastic or metal body is more reliable.

Frequently Asked Questions about Shut-Off Pneumatic Valves

What are pneumatic actuated shut-off valves used for?

Shut-off valves with pneumatic actuators are used in industry for reliable and quick blocking of liquid flow with high viscosity, density, and high pressure — viscous oils and petroleum products, various emulsions and chemical solutions, food syrups, etc.

What is a seat type shut-off valve?

Shut-off valves of the seat type are a type of sealing elements with a so-called "seat". This is the element in the valve's flow opening, creating a recess completely replicating the conical or semi-circular shape of the plunger head. When the valve switches to a closed state, the plunger sinks into the seat until it rests, and the pressure from the inlet side enhances the plunger's sealing against the seat, ensuring better tightness when flow direction in the valve is maintained.
