Working pressure according to GOST 5762-74 PN 1.0 MPa (10 kgf/cm2) with a margin of safety 1.8 MPa We produce cast iron gate valve (wedge gate valve - gate valve-parallel) two-disc with rising stem designed for use as shutoff devices at pipelines for transportation of water and steam to the flow of the environment. Designed for installation in piping engineering. Dignity — Simplicity of design, reliability in operation. — The use of brass in sealing shutter allows you to operate cast iron gate valves for a long time. — A packing gland cast iron gate valves allows to change or retrieve the seal when the shutter is open. — Acceptance of hydraulic testing of valves is cast iron stands with water pressure up to 1.5 MPa, in accordance with the specifications and standards.
