HK59-D Cast Iron Pneumatic Actuator Operated Butterfly Valve

COVNA pneumatic actuator NPT 2″ cast iron single acting or double acting butterfly valve. The body is cast iron and internals are made of stainless steel and the sealing material is made of EPDM. What’s more, stainless steel body material and PTFE seal are also available. It is not only suitable for universal liquid but also corrosive liquid,which make it usable for more fields. It is used for being connected with pipeline needed to be paused frequently. It is popular in industrial automatic control system of food, environment, paper making, chemistry,etc.

  • Model: HK59-D
  • Size Range: 2''~16''
  • Pressure Range: 1.0MPa to 1.6MPa
  • Material: Cast Iron

EPDM Seated Air Operated Wafer Type Butterfly Valve 

  • This butterfly valves are smaller, lighter and larger caliber, more economical than other valves.
  • The pneumatic actuator can be switched on and off quickly when it rotates 90 degrees, easy to operate.
  • Water line design of sealing seat and plane design of sealing surface of valve plate completely avoid clamping phenomenon of pneumatic valve caused by long time opening.
  • Spherical frictional surface design is adopted at the middle and lower holes of the valve plate. The torque is smaller and the sealing performance is better.
  • The seat has no back-to-back design, lighter torque, and is convenient for users to replace the seat by themselves.
