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. It boasts ease of installation, maintenance, and online inspection of instruments. The valve group ensures seamless integration and operational efficiency.
i
It can be divided into 2-valve, 3-valve, and 5-valve groups based on their functions, and into P type,
flat type, T type, H type, and cylinder stop valve based on their structure.
Integrated Valve Group
This setup assembles the transmitter and the valve group at the factory, followed by a comprehensive pressure and leakage test. This reduces the on-site installation process and prevents leakage caused by transmitter installation.
Valve Group Features
· Safety Stop Pin
Utilizes 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
Employs hard sealing between stainless steel components, ensuring safety and reliability.
· Valve Core
The valve core components use a segment structure, enhancing the sealing performance, service life, and handle management of the valve group.
· 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. Despite having different sizes and markings for various functions, they share the same structural features.
