Pneumatic Actuators for Corrosive Environments
Hayward Flow Control announces the launch of its glass filled polypropylene (GF-PP) PMD4/PMS4 series pneumatic actuator line, which features a GF-PP housing that provides superior corrosion resistance and performance in environments and atmospheres where most metal actuators cannot. According to the company:
- With the GF-PP material, the actuators are very robust, lightweight and compact, allowing for ease of installation.
- The actuators are available in several sizes for use with Hayward ball valves up through 6 inches, and butterfly valves through 4 inches.
- Available in both double-acting and spring-return designs, the PMD4 has a torque range at 80 psi supply, from 125 in-lbs to 500 in-lbs, whereas the PMS4 features a range of 44 in-lbs to 230 in-lbs.
- All sizes have NAMUR VDI/VDE 3845 mounting for solenoids and ISO5211 mounting base.
