JY42W Copper oxygen valveDetailed product description：

Structural characteristics of JY42W copper oxygen valve
For nominal pressures PN ≥ 1.6MPa and DNl25-200, an internal bypass structure is adopted; DN250-500 adopts a structure with an external bypass valve. The purpose is to reduce the pressure difference between the front and back of the valve to avoid high flow rate, high erosion, and prevent high temperature, thereby ensuring the safe operation of the oxygen pipeline network and reducing the operating torque.

Medium flow direction: For PN ≥ 1.6MPa and DN ≤ 100, the medium flows from below the valve disc into above (i.e. low inlet and high outlet), while for DN ≥ 125, the medium flows from the valve disc into below (high inlet and low outlet). For valves with DN ≥ 125, the medium flow direction of high inlet and low outlet is adopted, which meets the structural requirements of the internal bypass valve and greatly reduces the closing force of the valve due to the pressure of the medium.

The valve is equipped with a static electricity safety device to prevent sparks from being generated due to static electricity.
Compared with ordinary shut-off valves, the support part of the shut-off valve for oxygen pipelines adopts a fully enclosed structure, and the protective cover plate on the support can be opened when the packing is compressed, which plays a role in preventing oil and dust. And there are obvious oil prohibition signs.
All parts undergo strict degreasing treatment
