Transmitter Accessories
Valve Group Brief Introduction
The valve group is primarily utilized for the initiation, shutdown, pressure balance, and discharge of input signals for differential pressure, pressure transmitters, and flow transmitters. Designed for seamless installation, effortless maintenance, and convenient online instrument inspection, this valve group ensures optimal operational efficiency.
di
vided into 2 valve groups, 3 valve groups, and 5 valve groups based on their functions, and categorized into P type
(Flat type), T type, H type, and cylinder stop valve based on their structural design.
Integrated Valve Group
The transmitter and valve group are pre-assembled and undergo comprehensive pressure and leakage tests at the factory. This pre-assembly minimizes on-site installation complexity and mitigates leakage risks associated with transmitter installation.
Valve Group Features
·Safety Stop Pin
Incorporates a stainless steel pin to securely prevent the valve seat from detaching from the valve body.
·Valve Body Design
Features an integrated structure that offers high strength and exceptional reliability.
·Valve Seat Sealing
Utilizes hard sealing between stainless steel components, ensuring safety and reliability.
·Valve Core
The valve core components are designed with a segmented structure, enhancing sealing performance and longevity. Additionally, the handle's operability is significantly improved.
·Lubricating Grease
Imported grease is applied between the sealing washer and the adjusting screw to minimize friction and enhance sealing performance.
.
Structural Features
The valve groups are managed by stop valves, discharge valves, and balance valves. Despite varying functions, the valves share consistent structural features, with distinct sizes and markings to denote their specific functionalities.
