All cylinders manufactured by NPV mount directly to our valves eliminating need for an adapter plate. All gates are machined to adapt to manual or automated operation
Cylinder barrels are manufactured of a lightweight, high-strength, corrosion-resistant composite material, designed and specifically for adverse environments
All cylinder operated valves supplied with Stainless Steel lockout bar and limit switch brackets
Piston seal is an elastomer quad seal providing longer life and positive seal compared to a standard o-ring seal
Cylinder stem seal is a U-cup design protected by a scraper for longer life and positive scaling
Length of lower cylinder bridge serves as guide for stem, reducing any slide torque and extending seal life
When used on high cycle scavenger valves, extra precaution is taken to prevent stem and clevis coming apart by threading and pinning the connection
Cylinders are easily field repairable by replacing complete soft goods kit which includes o-rings, quad seal, wiper and u-cup
NPV valves are designed to accept a new cylinder or convert manual valve to automated operation in line but under ZERO line pressure
Due to light weight construction of all NPV cylinders and the strength of 4-post topworks, most installations do not require additional support
