Steam Gate Valves

The gate is usually wedge shaped.

Steam gate valves.

Packing rings are precompressed to 4000 psi to provide a high integrity seal. When the valve is wide open the gate is fully drawn into the valve bonnet. Thermal expansion of the steam line sometime causes distortion of valve bodies which may lead to thermal blinding. The flexible gate allows the gate to flex as the valve seat compresses due to thermal expansion of the steam pipeline and prevents thermal blinding.

Gate valves are used when a straight line flow of fluid and minimum flow restriction are needed. Gate valves use a sliding plate within the valve body to stop limit or permit full flow of fluids through the valve. Also known as gate valves these gradually open and close to prevent system damage from suddenly starting and stopping flow. Steam is also used for cleaning heating and humidification.
