Reverse Flow Control Valve PTP45013-050 for Optimal Flow Control

The gate is controlled by the flow of the working medium: in case of no pressure or reverse flow of the working medium, the disc rotates on the axis, falls on the sealing surface of the body seat (under its own weight, weight of the counterweight or under the action of the reverse flow of the medium) and closes the passage section of the gate, creating an obstacle to the reverse flow of the medium
