Automatic valve with pneumatic control is designed to operate as remote control locking device for fluid or gas flows in pipelines. Valves are used to organize pulseless fluid flow in laboratory pumps and to automate experiments on laboratory equipment.
The valve locking element is a needle. Valve closing/opening occurs when compressed air is supplied to the working cavity, activation takes place in less than 0.1 seconds. Additional electromagnetic valves are used to control compressed air flow.
Pneumatic valves have a constant volume design in which internal fluid volume does not change while opening / closing. Two-way and three-way valve models are available.
