Transmitter Accessories
Valve Group Brief Introduction
The valve group is primarily utilized for the start, close, pressure balance, and discharge of input signals from differential pressure, pressure transmitters, and flow transmitters. It offers effortless online installation, maintenance, and inspection of the instrument. The valve group can be divided into
2,
3, or 5 valve groups based on their functions, and by their structural designs into P type
(Flat Type), T Type, H Type, and Cylinder Stop Valve.
Integrated Valve Group
Assemble the transmitter and valve group in the factory, conducting a comprehensive pressure and leakage test. This significantly reduces the on-site installation process and prevents leakage caused during 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, ensuring high strength and reliability.
·Valve Seat Sealing
Hard sealing with stainless steel, ensuring safety and reliability.
·Valve Core
The valve core components feature a segmented structure, enhancing sealing performance and service life, while improving handle operation.
·Lubricating Grease
Imported grease is applied between the sealing washer and the adjusting screw, reducing friction and improving sealing performance.
.
Structure Features
