Feature:

Double eccentric structure design. The uniquely designed lip sealing structure achieves zero leakage of two-way bubble level under elastic interference and self-sealing.
Interchangeable PTFE seats can be used in a variety of different working conditions to achieve long service life and effect.
Anti-blowout valve design.
Under the working condition of fugitive medium, the low-leakage carbon fiber bowl type combined with packing structure can be adopted to meet the requirements of ISO15848 and API622 standards.
The tangential pin of the valve stem is half on the valve plate and half in the valve stem, and the tangential positioning makes the squeeze force of the valve plate and the valve instead of the shear stress, making the connection more reliable.
Equipped with ISO 5211 standard connecting plate, pneumatic device, electric device, gas-liquid linkage device and other remote control mechanisms can be installed for automatic control system.
