DXSS-M3F8-FL flange three-valve

The valve group is composed of high and low pressure valves and balance valve groups, and its function is the same as QFF3. The connection method of the pressure point is a card sleeve type or a welding type, and it is directly connected to the transmitter through a flange, which reduces leakage points and facilitates installation.

DXSF-1 type three valve group

This valve can be installed on the arterial pipeline where the flow test instrument needs to be transmitted remotely. It consists of two pressure taking valves and a balance valve, which facilitates the establishment of the instrument control circuit.

DXSF-2 type three valve group

The valve group can be directly installed and used in combination with differential pressure, pressure instruments or transmitters. The differential pressure port can also be directly connected to the pressure pipe joint. The center distance between the two joints is 35mm.

DXSF-3 type three valve group

This valve group can be directly installed and used with differential pressure, pressure instruments or transmitters. The differential pressure port is connected to the pressure guiding tube through a waist flange. The center distance between the two joints is 54mm.

DXSS-M3F8 three-valve internal thread

The valve group is designed by referring to the three valve group in Singapore. It has a compact structure, good sealing performance, easy installation and use, and the valve group comes with adjusting holes, which can be directly fixed on the mounting bracket to facilitate disassembly.

DXQFF3 type three valve group

QFF3 type three valve group is composed of high and low pressure valve and balance valve group, which is used together with differential pressure transmitter. Its role is to connect or disconnect the positive and negative measurement rooms of the differential pressure transmitter to the pressure point, or to disconnect and conduct the positive and negative pressure measurement room. The pressure and pressure points are directly connected to the steel pipe. Welding, or other connection methods can be used.

DXWF1 / 2 type five valve group

WF1 / 2 type five-valve unit: This valve is suitable for all kinds of imported instrumentation devices. It is installed with various differential pressure, flow, liquid level and other transmitters. The blowdown) valve combination is a rest. When working, the two sets of check valves and the balance valve are closed. For inspection, just cut off the high and low valves, open the balance valve and open the two check valves, and then close the balance valve. The transmitter can be calibrated or balanced online.
