SY Series Electric Trap


The valve body is forged Y-shaped, with low flow resistance, large Cv value and fast exhaust speed.

There is a throttle plate on the valve core, which effectively protects the sealing surface and prolongs the service life of the valve.

The valve core and seat are surfacing with hard alloy, which is treated and processed by a special process to prevent cavitation and erosion.

There are two guide rings on the valve core, the valve stem is balanced in force, and the action is flexible, and it is not easy to jam.

The stem packing is all imported high-quality Monel flexible graphite packing imported from the United States. It has good chemical and flexible properties, low friction, zero leakage and long service life.

There are heat sinks on the valve cover to fully dissipate heat to ensure that the execution structure and solenoid valve will not be affected by high temperature and fail.

The middle cavity gasket is a high-mesh flexible graphite gasket with a wire, which has better sealing characteristics and reliability than general flexible graphite gaskets.
