Industrial Applications

1. Quarter-Turn Actuator Integration

The reducing sleeve seamlessly adapts an SW22 actuator drive output to an SW14 valve stem. This enables direct mechanical coupling of large quarter-turn pneumatic actuators with smaller ball or butterfly valves without requiring custom-machined brackets or couplings.

Problem Solved

Mismatched drive shaft dimensions between standard pneumatic actuators and process valves prevent reliable, slip-free torque transmission.

2. Corrosive Fluid Control Systems

Constructed from high-density sintered stainless steel with a CRC 2 rating, this reducing sleeve withstands moderate condensation and occasional chemical exposure, ensuring long-term automated actuation in water treatment and filtration skids.

Problem Solved

Standard carbon steel drive adapters rapidly rust and seize when exposed to ambient moisture or light industrial washdowns in fluid handling environments.

3. Automotive Paint Shop Valve Automation

Utilizing its strict VDMA24364 zone III LABS conformity, this adapter drives fluid supply valves inside automotive paint lines without releasing airborne silicone or outgassing contaminants.

Problem Solved

Standard mechanical components introduce paint-wetting impairment substances (PWIS) into the environment, causing fish-eyes and defects in automotive paint finishes.
