Knife gate valve type is simple and compact structure, reasonable design, lightweight materials and reliable sealing, flexible and convenient operation, small volume, smooth channel flow resistance, l

wafer knife gate pneumatic optional accessories 1, single or dual controlled solenoid valves (24V, 220V and other voltages are available, if necessary, select the explosion proof solenoid valves);

In their simplest construction, gate valves have a valve stem, or spindle, which projects from the waterway to the outside atmosphere, for controlling the gate.

Gate advantages: (1) fluid resistance small because valve body internal medium channel is the direct, medium flows when the valve without changing its flow direction, so fluid resistance.

Gate valves can be used in liquid or gas services to isolate the downstream line from the upstream.

Gate valves in parallel is usually referred to 'Knife. Single disc valves (gate) is used when not needed to achieve high integrity.

The rising stem gate valve and the Non-rising stem gate valve

In our experience, to extend the life of the gate valve, should be concerned with the following several points.
