Overview

ASEPCO Weirless Radial diaphragm™ in-line valve

With accelerated diaphragm change over and easy maintenance, the new weirless in-line valve series from ASEPCO valves has been developed with time and cost savings in mind.

One minute diaphragm change-over
Compatible with EPDM and Silicone diaphragm options
Flexible installation angles for unobstructed flow path and operator safety
Defined shoulder seal minimizes contaminant entrapment

Composed of a forged body, the in-line valve is designed to provide a less restrictive fluid path over traditional weir style valves. The weirless in-line valve also eliminates the potential of trapping impurities through our innovative shoulder seal design.

Every surface material that touches your process fluid is manufactured to comply with multiple global industry standards, safeguarding you and your process.

Features and benefits

Radial diaphragm - eliminates entrapment for easy cleaning
Fully drainable within a 180 degree range of installation angles
Simple, Tri-Clamp assembly makes maintenance 80 % faster compared to a weir type valve
Integrated travel stops
No readjustment or retightening
