Technical Parameters Category Parameter Specification / Description General Model 95H-109 Type Piston Actuator Series 95H Performance Action The "109" code commonly specifies a Spring-Return (Single-Acting) design, providing a fail-safe mode. Piston Diameter The "H" in 95H and the "109" code indicate a specific, large piston diameter capable of generating high thrust. Stroke Length Defined by the "109" code. This is a specific linear travel distance (e.g., 2 inches, 4 inches). Supply Pressure Typically up to 120 psig (8.3 bar). Thrust Output Very High. Exact thrust (in lbs or kN) depends on supply pressure and piston size, but this model is designed for demanding applications. Spring (if applicable) Spring Range For spring-return models, the "109" defines a specific spring that determines the fail-safe action and the air pressure required to compress it. Construction & Environment Body Material Cast Iron or Ductile Iron. Piston Rod Material Stainless Steel. Temperature Range Standard: -20°F to 150°F (-29°C to 66°C).
