Product Description
Two-Valve Group
Two Valve Group combine several valves in one body with multiple connections. This equipment assists pressure instruments directly and indirectly in measuring and equalizing pressures, differential pressures, static, gauge, and variable in process instrumentation lines by bleeding, blocking, and calibrating.

Xinyi Instrument supplies pressure transmitters for process control, hydraulic systems, petrochemical plants, water treatment, HVAC, power generation and general industrial pressure monitoring. Our pressure transmitter range covers gauge pressure, absolute pressure, differential pressure, high temperature media and digital communication applications.
Choose from compact pressure transmitters, smart 3051 differential pressure transmitters, diaphragm seal models, RS485 digital pressure transmitters and high frequency dynamic pressure sensors. Standard outputs include 4-20 mA, voltage output, HART and RS485 Modbus options, with stainless steel wetted parts and custom process connections available on request.
| Pressure Types | Gauge, absolute, negative pressure, differential pressure |
|---|---|
| Measuring Range | From low differential pressure to high pressure ranges up to 100 MPa, depending on model |
| Output Signals | 4-20 mA, 0-5 V, 1-5 V, 0-10 V, RS485 Modbus, HART options |
| Accuracy | Typical options include 0.1%, 0.2%, 0.25% and 0.5% FS |
| Process Connection | M20 x 1.5, G1/4, G1/2, NPT and customized thread connections |
| Wetted Materials | Stainless steel, 316L diaphragm and corrosion-resistant sealing options |
| Media | Water, oil, gas, air, steam and compatible liquid or gas media |
| Applications | Pipeline pressure, tank level, flow differential pressure, hydraulic pressure and automation systems |
A pressure transmitter converts the pressure of liquid, gas or steam into a standard electrical signal for PLC, DCS, recorder or control instrument input. It is widely used for pipeline pressure, tank level, flow measurement and process safety monitoring.
Confirm the pressure range, pressure type, medium, temperature, output signal, accuracy, installation thread, electrical connection and environmental requirements. For corrosive media, high temperature or sanitary applications, diaphragm material and sealing structure are especially important.
Gauge pressure transmitters measure pressure relative to atmospheric pressure. Absolute pressure transmitters measure pressure relative to vacuum. Differential pressure transmitters measure the pressure difference between two points and are commonly used for flow, filter and level measurement.
Yes. Xinyi Instrument can support customized pressure ranges, process connections, output signals, cable length, display options and model selection for different industrial applications.
