Product features：Pressing transmission mechanism adopts a synchrono
The structure characteristics and uses:
The valve is closed design structure, the valve body adopts a totally enclosed type shell, but the operating process of gas pipeline leakage, avoiding pollution to environment, has good external pitpipeline strength, setting of pneumatic device in the external, in order to maintain the check, the people close to operate safety performance is high, the disadvantage is the replacement of rubberring is trouble.
Characteristics of the valve designed to absorb the foreign flashboard valve float valve plate;pressing transmission mechanism adopts a synchronous clamping mechanism of multi point, has the characteristics of good sealing performance, reliable work, convenient repair.
