Essential Transmitter Accessories
Concise Valve Group Introduction
Our valve group is primarily utilized for initiating, closing, achieving pressure balance, and discharging the input signals of differential pressure, pressure transmitters, and flow transmitters. This assembly ensures effortless installation, maintenance, and online inspection of instruments. Our valve group is designed for efficiency and reliability.
Di
vided into 2-valve groups, 3-valve groups, and 5-valve groups based on their functions, as well as P type
(Flat type), T type, H type, and cylinder stop valve depending on their structural design.
Integrated Valve Group Solution
Transmitter and valve groups are meticulously assembled in our factory, where they undergo comprehensive pressure and leakage tests. This process minimizes on-site installation procedures and prevents leakage commonly associated with transmitter setup.
Outstanding Valve Group Features
