Features:
 
 
Surface coatings:
Surface epoxy coating powder has been tested by UL/FM laboratory, completely meeting the requirements of UL262/FM1120 and 1130 to ensure the product quality
 
Stable rubber performance:
After 6 minutes high-flow speed test and life test, the rubber shall have no cracking, permanent deformation or break away from the wedge, ensures the valve is with reliable sealing performance and long service life
 
High-mechanical strength:
Under the maximum torque operating, no part shall be damaged, ensuring the good functioning of the valve with electric actuator even when momentary high torque input
 
High-strength body:
Body of casting using the ductile iron with good strength characteristics, under the high-pressure testing (DN50-DN300 4 times rated pressure), there is no leakage or shell cracking
 
ACME threaded stem with low operating torque
 
No groove on the bottom
Preventing deposit and reducing the flow-resistance, ensures reliable sealing
