What is a double acting piston seal?
A double action piston seal is a seal that had been designed to contain pressure on both sides of a piston, thus preventing leakage and allowing maximum mechanical effort to be applied to moving the piston along the bore of a cylinder.
How does a double acting piston seal work?
The seal is intended to prevent leakage across the piston, causing maximum efficiency of system. Pressure is applied from either direction of a double acting piston seal, to drive the ram that the piston is fixed to both in and out or stop it in a controlled position.
How to choose your double action piston seal
Double acting piston seals can be driven either hydraulically (double acting hydraulic piston seals) or pneumatically (double acting pneumatic seals), with appropriate seal designs for each system, and application. When it comes to choosing the most suitable double action piston seal for your project, it is important to consider many contributing factors of the application, including:
- Pressure expected
- The friction losses acceptable
- Whether the piston head is integral or split
The design of the double acting piston seal head will dictate what type of double action piston seal profile and material can be used on the application. Many high-pressure systems require stiff, robust double acting piston seals to control the action of the piston seal.
