Pneumatic valves of the KB series for high pressure
IS AN EXCLUSIVE SOLUTION FOR WORLD CLASS LABORATORIES
Recently, there is a growing need for rapid streams switching of compressed to high-pressure gases. The new family of the KB-20-70, KB-40-70, KB-80-50 valves with operating pressure up to 7.0 MPa have almost the same opening / closing times, that its analogs KB-28-10, KB-40-10, KB-80-10, designed for industrial pressure up to 1.0 MPa.
The pneumatic diagram of such valves are shown below. Each of its forms the assembly of high-speed and starting valves (see the diagram below), which is controlled by a standard air-distributor designed to operate under the pressure up to 1.0 MPa.
