Russian standard flange gate valve

Working Principle of Russian Standard Rising Stem Flanged Gate Valves

he durable and reliable Russian standard rising stem flanged gate valve operates on the principle of rotating the valve stem to drive the gate's movement. The handwheel rotates the valve stem in place, and the trapezoidal thread at the bottom of the stem engages with the nut inside the gate, converting the rotational motion into the linear movement of the gate. Rotating the handwheel clockwise lowers the gate, pressing it against the valve seat to achieve a seal; rotating counterclockwise raises the gate, disengaging it from the flow path and opening the valve. The valve stem never rises or falls, only rotates, resulting in a small installation height. The main body is made of WCB, SUS304 (CF8), or SUS316L (CF3M), ensuring reliable sealing and suitability for shut-off control in Russian standard piping systems.

Product Parameters

Durable and Long-Lasting

Shenchi Russian Standard Exposed Stem Flanged Gate Valves feature all-metal internal components, with the internal metal material matching the body, eliminating weak points. The WCB cast steel valve body boasts high strength and impact resistance; the stainless steel material is corrosion-resistant, suitable for humid and corrosive environments. The valve stem's trapezoidal thread is precision-machined for smooth operation and minimal wear. The sealing surface is overlaid with copper alloy or stainless steel, offering erosion resistance and a long service life. Low price does not equate to low quality; Shenchi offers direct factory supply, eliminating intermediaries and providing outstanding value.

Application Scenario 1: Underground Pipelines Shenchi Russian Standard Exposed Stem Flanged Gate Valves feature a concealed stem design, with the valve stem not rising or falling, resulting in a low installation height, making them particularly suitable for space-constrained locations such as valve wells and underground pipe racks. The flange connection provides a reliable seal, with a pressure rating of PN16, suitable for municipal pipelines such as water supply, heating, and sewage. High-performance Russian Standard Exposed Stem Flanged Gate Valves, with an unexposed stem, are less susceptible to corrosion from soil moisture and impurities, maintaining smooth operation even after long-term underground use.

Application Scenario 2: Industrial Pipelines

Shenchi Russian Standard Rising Stem Flanged Gate Valves are suitable for industries such as petroleum, chemical, power, and metallurgy. Media include water, air, gas, petroleum, and liquids. Media temperature ranges include high, medium, normal, and low temperatures. WCB material is suitable for -29℃ to 425℃, while stainless steel material is suitable for a wider temperature range.
