Transmitter Accessories
Valve Group Brief Introduction
The valve group is primarily used for starting, closing, pressure balancing, and discharging the input signals of differential pressure, pressure transmitters, and flow transmitters. Its design ensures easy installation, maintenance, and online inspection of instruments. The valve group can be distinguished by its various functionalities and structure types.
i
vided into 2-valve groups, 3-valve groups, and 5-valve groups by their functions and P type
(Flat type), T type, H type, and cylinder stop valve by their structure.
Integrated Valve Group
The transmitter and valve group are assembled at the factory, followed by a comprehensive pressure and leakage test. This process minimizes on-site installation steps and prevents leakages that might occur during transmitter installation.
Valve Group Features
· Safety Stop Pin
Equipped with a stainless steel pin to prevent the valve seat from detaching from the valve body.
· Valve Body Design
Features an integrated structure with high strength and reliability.
· Valve Seat Sealing
Utilizes hard sealing between stainless steel components, ensuring safety and reliability.
· Valve Core
The valve core components feature a segmented structure, enhancing sealing performance and extending the valve group's service life. The handling of the handle has also been improved for better usability.
· Lubricating Grease
Imported grease is applied between the sealing washer and the adjusting screw to reduce friction and enhance sealing performance
.
Structure Features
The valve groups are controlled by stop valves, discharge valves, and balance valves. While valves with different functions have varying sizes and markings, they share the same structural features.
· Versatile Mounting Options
Adaptable plate type, flange straight mount, 1/2NPT joint, and seamless pipeline connection
· Robust Structural Materials
High-quality SUS316, SUS304, SUS321, HC-276, and more
· Signal Cap Features
Integrated stop valve, balance valve
and discharge valve
Valves adopt vibrant blue, green, and red signals for a fresh, natural appearance
· Durable Gland Packing
Utilizes PTFE and Graphite for superior performance
· Maximum Working Pressure
