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.
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.
