BUTTERFLY VALVES

Butterfly Valves

One of the most durable of all resilient-seated butterfly valves in the industry, this valve excels in a wide variety of applications. Cast in both wafer and tapped-lug patterns in a wide variety of material choices, DEMCO butterfly valves feature a one-piece body for minimum weight and maximum strength. The unique stem hole design in the disc ensures a dry stem journal and the hard-backed seat allows ease of installation, reliable operation, and is field-replaceable without special tools. DEMCO butterfly valves are available in sizes 2 in. through 36 in. (50 mm through 900 mm).

Engineered for long-term, maintenance-free performance, DEMCO butterfly valves are commonly selected for a variety of applications spanning a wide range of industries:

Bi-directional sealing
This valve provides bi-directional sealing at full rated pressure with identical flow from either direction.

Integral flange seal
Molded into the edge of the seat is an integral flange seal which accommodates ASEM weld neck, slip-on, threaded and socket flanges as well as “stub end” type C flanges.

ASME Class 150 rating
Body rating is ASME Class 150 (285 psi non-shock). Wafer body diameters are designed to self-center in ASME Class 150 flange patterns.
