HPD

Short Description:

The HPD high performance linear pneumatic diaphragm actuator adopts multi-spring structure, which make it with light weight, small volume and large output force. Its working principle is that the air source pressure enters the diaphragm chamber and acts on the diaphragm to generate a thrust, which causes the actuator push rod to move, and at the same time compresses the spring until it balances with the reaction force of the spring, so that the push rod reaches a predetermined position. HPD series linear actuator is suitable for linear motion control valve, proportional adjustment and on-off valves, and other linear motion devices etc.

Product Introduction

Features

●Application Versatility—Direct Action & Reverse Action in six sizes are available for an extensive variety of applications. Spring ranges, stroke limits, and manual overrides are available for nearly any control valve application.

●Excellent Linearity Between Loading Pressure and Stroke — A molded diaphragm travels in a deep diaphragm casing, the effective area of the diaphragm changes very small, which provides excellent linearity.

●High Thrust Capability—The molded diaphragm and cold stamping case allows high pressure supply and maximum thrust for given diaphragm size.

●Long Service Life—cold punched sheet metal casing cap and ductile iron construction provides increased stability and protection from corrosion and deformation should over-pressurization occur.

●Cold Service Application—Enhanced product specification for all sizes of HPD series diaphragm actuators allow performance to -40℃ if required.

●Positive Connections—A split block stem connection provides a solid transfer of motion while allowing easy mounting. The absence of linkages helps to avoid lost motions and inaccurate valve positioning.

●Compact&Light—With the multiple springs and a high air supply pressure, HPD series are much more compact and light as compared with conventional actuators.
