Product Overview

Paladon Americas PNL and HYL Series Piston Linear valve actuators are designed specifically to control all makes and sizes of rising stem valves such as gate and control valves.When designing this next generation of pneumatically and hydraulically powered linear actuators we set ourselves the following fundamental targets:

• To have a compact and reliable valve actuator
• To achieve a highly modular design permitting easy field maintenance and easy application to the various valves to be automated
• To accommodate the most current customer driven design requirements in terms of performance reliability, corrosion and environmental resistance, and maintenance free life

Product Features and Benefits

• Available in double acting or spring return (fail safe) configurations
• All steel construction with no external threads
• Totally enclosed weatherproof housings, certified to IP66
• Scragged springs (set removal) ensure optimum performance and reliability
• Electroless nickel plated cylinders as standard; chrome, Xylan or electrofilm coatings are also available
• EN ISO 5210 valve interface Valve stem position indicator can accommodate position switches or transmitter
• All actuators are fitted with lifting lugs and control accessory mounting pads
• Available with optional hand wheel, gearbox or hydraulic manual overrides

Valve Mounting Options

• Pedestal-The standard valve mounting design uses a pedestal or a yoke to mount the actuator above the valve from the valve bonnet bolting
• Compact-Where space is at a premium, this design allows the actuator body to be directly mounted on the valve body, thus eliminating the height incurred when using pedestal type mounting
• Integral-Incorporates the valve bonnet and back seat into the end cap of the actuator, with the valve stem being completely integral with the actuator
