Overview Paladon’s PN and HY-Series of pneumatic and hydraulic scotch-yoke actuators have been designed specifically to guarantee long cycle life in the most demanding applications and environmental conditions. A fabricated steel frame, coupled with an all-steel construction, results in a lighter and more corrosion resistant actuator than traditional ones that employ castings. A light design, superior corrosion resistance and an Ingress Protection rating of IP66 as standard, makes the PN & HY Series an ideal choice for offshore applications, or any other in which weight and corrosion resistance are critical design considerations.
Applications Automation of any quarter-turn mechanism; including ball, butterfly & plug valves and louvers & dampers

Key Features & Benefits
Electroless nickel plated cylinder as standard with hard chromium plating, Xylan® or Electro-film available
Springs contained within a fully welded canister (which is post weld heat treated) to guarantee simple and safe removal
Springs are scragged (set removal) in order to warrant optimum and stable performance
Easy and economical maintenance due to simplified design, no special tools required
Compliant to PED 97/23/EC.
Modular construction means greater flexibility when selecting cylinder/spring combinations, and reduces production downtime during field servicing
Several yoke lever configurations (cants) allowing selection of the actuator output torque that best suits the valve torque characteristic.
Suitable for high frequency and high speed operation
Guide bar frame design used to eliminate side forces and low friction seals ensure high efficiency
Oil prices fell May 15 in the New York market as benchmark US crude came under heavy selling pressure from the economic and political turmoil in Europe that also undermined the equity market.
Statoil is transferring operatorship of Vilje oil field offshore Norway to Marathon Oil Norge, effective Sept. 1 if approved by the Norwegian Ministry of Petroleum and Energy.
