2-Way & 3-Way
Wafer and Lug Style Bodies
For Mixing & Diverting, Hot & Chilled Water, Steam & Special Applications
SERIES 31
Bray Controls is proud to offer this automated line of butterfly valves. The Series 31 is available
in a lug or wafer style body. Designed for general applications, this valve features long service life, ease of parts replacement, and interchangability of components.
Bray’s high quality automated butterfly valves precisely regulate
the flow of hot and cold water or steam through all types of coils and heat exchangers.
The Series 31 2-Way valves have an equal percentage flow characteristic. The 3-Way valves have a liner flow. Both offer a very high rangeability and bubble tight shut-off capacity, and feature ease of installation and maintenance.
Optional Features Include:
- Aluminum Bronze discs
- Cast Steel bodies
- Fluoroelastomer Seats for high temperatures up to +400°F.
The Bray Series 31 offers a thin-profile disc without disc/stem fasteners to obstruct the flow. This design eliminates possible leak paths and allows for high Cv values with reduced turbulence. Stem design provides blow-out proof protection.
Most of Bray’s electric and pneumatic actuators direct mount to Bray’s butterfly valves, reducing space requirements.
SERIES 41 High Performance
The Series 41 offers bidirectional, zero leakage, shutoff at full rated ANSI Class 150 operating
pressures. Rated 150 psi saturated steam at 366°F for on-off applications and 50 psi at 300°F for modulating service. The simple, innovative design offers rugged reliability and easy maintenance.
