Gate Valves
Gate Valves are designed to provide minimum turbulence & resistance to flow when in fully open position. These gate valves ensure accurate control & alignment of wedge while operating. The gate valve is a general service valve used primarily for on–off, non-throttling service. The valve is closed by a flat face, vertical disc, or gate that slides down through the valve to block the flow. With detailed information on the right application and operation of the gate valves, one can easily install and use a gate valve. There are various models currently selling in the market today. However, it is important that one checks out for the right gate valve for his or her system. Selecting a gate valve requires proper understanding of one’s piping system where it is to be applied. Ensure the pressure and size proportions are in place before settling on a specific type of gate valve. Depending on the environment of use, one may opt to go for either brass or steel gate valve. Plastic gate valves are cheaper to acquire though they may not be effective for high pressure systems, as well as corrosive environments.
