RXBF High pressure pneumatic back pressure valve

Working principle of rxbf high pressure pneumatic back pressure valve produced and sold by Wo valve (Shanghai) Co., Ltd.:

The rated pressure can be adjusted, generally by adjusting the ejector rod at the upper end of the spring, so as to adjust the length of the spring.

The fluid enters from the inlet of the back pressure valve and is blocked by the diaphragm, so the fluid generates upward pressure on the diaphragm.

When the pressure is large enough, the spring is compressed, and the fluid pushes up the diaphragm to form a channel and flows out from the outlet of the back pressure valve; If the fluid pressure is not enough, it will form pressure holding, increase the inlet pressure until it reaches the rated pressure, and jack up the diaphragm to form a channel.

Detailed introduction of rxbf high pressure pneumatic back pressure valve

The maximum bearing pressure is 400bar, the maximum control pressure is 250bar, and the CV value is 3.84-7.3. Interface 1 "- 1 ?” Thread or flange. All 316L stainless steel, can be used for various media.

Rxbf high pressure pneumatic back pressure valve product features:

1. The back pressure valve is not a safety valve. Open the back pressure valve for pressure relief when the pressure slightly exceeds the set value, and close the valve when the pressure slightly falls below the set value.

2. Large diameter, large flow and atmospheric chamber are conducive to improve pressure stability.

3. Large diaphragm sensing pressure, balanced valve seat, accurate pressure control.

4. All 304 / 316 stainless steel, with a variety of optional sealing materials, suitable for any medium.

Model of back pressure valve:

When selecting the back pressure valve, the following parameters and data must be determined:

1. Pressure range to be set;

2. Inlet and outlet connection mode: common connection modes include internal thread, flange and hose joint;

3. The diameter of the required back pressure valve is generally the diameter of the pump outlet;

4. Conventional materials include: PVC, 304, 316, 316L stainless steel, carbon steel, etc.
