Blow-Down Valves are used to remove impurities from boiler water. The water is blown out of the boiler with force by the steam pressure within the boiler. It needs to be blown out at speed, so that solid impurities in boiler feed water are carried out with it.

Unsourced material may be challenged and removed. A gate valve, also known as a sluice valve, is a valve that opens by lifting a barrier (gate) out of the path of the fluid. Gate valves require very little space along the pipe axis and hardly restrict the flow of fluid when the gate is fully opened.

Description: Resilient seated ductile iron gate valve also commonly known as a sluice valve. The gate valve is manually operated by a non rising stem handwheel operation (clockwise to close) made in accordance with AS2638
