HM Series Rolling Diaphragm Pneumatic Actuators
Sizes: HM280, HM530, HM530D, HM960, HM960D, HM960T.
Max Operating Air Press: 6 Barg
Operating Temperature Range: -25°C ~ 120°C
Range of Thrust (N) : 1,536 ~ 50,508.
Stem Travel Range: 0 ~ 75mm
Rolling Diaphragms have been type Tested with over 1,000,000 cycles.
Features & Benefits
Lifting eye bolts
Lifting eye bolts are fitted for the convenience of fitting the actuator to the valve body. They are not designed for lifting the combined valve and actuator. For larger
sizes of control valves a separate lifting points are included on the valve body.
Cast Diaphragm Housing
The actuator diaphragm housings are made of precision cast Aluminium alloy ACD12 or carbon steel A216WCB.
Actuator Pillars
Actuator Pillars are made of Duplex Stainless Steel.
Stem Connection
Stem Connection is via a screwed adaptor secured with a block clamp.
Diaphragms
Diaphragms are made of Neoprene and nylon mesh which has been type tested to over 1 million open/close/open cycles without failure.
Hazardous Chemical Environment
Hazardous Chemical Environment compatible with A4 marine grade bolting to resist corrosion.
Accessories
Accessories are available to suit customer requirements and specifications and are supplied fitted to the valve.
Selection
Each actuator is selected to match each control valve or actuated ON/OFF valve by our team of engineers. The criteria of valve size, valve trim, application fluid,
pressures, temperatures, pressure differential, amount of supply air pressure and travel required are all taken into consideration. FAT testing and documentation are all registered at the factory before delivery.
Maintenance
Maintenance is easily carried out with easy access to all internal parts via the actuator cover. All replacement parts are available as required. The pre-tensioned springs within the actuator are safety released via the extended bolts on the actuator cover.
Manual Override Handwheels
Manual Override Handwheels are available as an option to provide an extra level of safety in the event of a loss of electrical or pneumatic power. See below
