Hollysys Pneumatic/Electric Soft/Hard Seal Flange/Wafer Connected A400 Eccentric Half-Ball Valve

Product Description

Application
·  Complying with GB, ANSI and other standards
·  Control valves for process industry and industrial application
·  Nominal diameter: DN25 to DN300, NPS V to 12"
·  Nominal pressure: PN16 to PN63, ASME CL150 to CL300
·  Temperature range:-100° C to +525° C

Features
·  Adopt the eccentric design that effectively reduces wear and tear and features light weight, large flow capacity, and excellent regulating and cutting performance
·  Small opening and closing torque and the flexible arm that produces small elastic deformation and elastic tightening force under the action of the actuator's thrust, thereby making the contact between the valve core and the valve seat more compact and firm and featuring good sealing performance
·  Special hardening treatment beneficial to flushing resistance
·  Suitable for sewage and other working conditions containing solid particles and oil slurrie

Supported Actuator
Matching with 830 angle actuator/A840 actuator
