The three-valve assembly consists of three interconnected valves. Based on the function of each valve in the system, they can be classified as follows: the left valve is a high-pressure valve, the right valve is a low-pressure valve, and the middle valve is a balancing valve. The three-valve assembly is used in conjunction with a differential pressure transmitter to connect or disconnect the positive and negative pressure measurement chambers from the pressure tapping point, or to disconnect or connect the positive and negative pressure measurement chambers.

The closing member of a globe valve is a plug-shaped valve disc with a flat or conical sealing surface. The valve disc moves in a straight line along the centerline of the valve seat. The valve stem can be of a lifting-rotating type, suitable for controlling the flow of various types of fluids, including air, water, steam, corrosive media, slurry, oil, liquid metal, and radioactive media. Therefore, this type of shut-off valve is highly suitable for use as a cutoff, regulating, or throttling valve.

Stainless Steel Diaphragm Pressure Gauge
Diaphragm pressure gauges are suitable for measuring the pressure or negative pressure of various fluid media that are corrosive, non-solidifying, or non-crystallizing.
Structural Principles
Structure: A diaphragm pressure gauge consists of four main components: the diaphragm assembly, the movement assembly, the pointer assembly, and the housing connection assembly.
Principle: The diaphragm pressure gauge uses a diaphragm as the instrument's rigid element. When the pressure of the measured medium acts on the diaphragm, it causes a displacement. This displacement is then transmitted through the movement assembly and pointer assembly, clearly indicating the measured pressure on the dial.
Technical Parameters
Accuracy Class: 2.5
Operating Environment Temperature: -40°C to +70°C; relative humidity not exceeding 90%.
Temperature Effect: When the operating temperature deviates from 20±5°C, the temperature-induced error does not exceed 0.04% per degree Celsius.
Mounting Position: Vertical installation
Housing Protection Rating: IP64
