Focus On Bray Butterfly Valves

Focus on Bray Resilient Seated Butterfly Valves

Valves Online are the official online partner for Bray. Bray valves are industry certified and trusted by thousands of businesses worldwide for their reliability and proven design features. With valves including Resilient Seat, Double Offset, Fire Safe Butterfly Valves & Bray/VAAS Knife Gate Valves.

Focusing on our Bray resilient seated butterfly valves in this post, we want to show you a selection of valves with some key features and benefits that we can offer in the Bray range

INTERNATIONAL COMPATIBILITY

Valve mounting top flanges meet ISO 5211 bolt circle standards for direct mounting of manual operators and power actuators. All Bray valves have extended necks which allow for at least 2” piping insulation.

ACTUATOR MOUNTING

All Bray actuators including handles, gear operators, pneumatic and electric actuators mount directly to Bray resilient seated valves. No brackets are required. This allows for simple installation in the field, minimizes possible misalignment and reduces overall height.

ISOLATION FROM LINE MEDIA

Bray’s seat design and internal disc to stem connection isolates the line media from the body and stem.

INTERNAL DISC TO STEM CONNECTION

Series 30/31 Sizes 2”– 20” (50mm–500mm) Bray offers Double "D" precision machined flats on the stem and in the disc. The Series 30/31 internal, non-wetted connections eliminate exposed external disc to stem connections.
The disc and the stem connection minimizes hysteresis and produces maximum strength engagements. All stem designs incorporate a blowout proof feature.

Stem connection

SEAT DESIGN

The seat is designed to seal with slip-on or weld-neck flanges and the molded o-ring eliminates the need for flange gaskets. The tongue and groove locks the seat in place and makes the valve dead end capable.

POLYESTER COATING

The Bray standard polyester body coating is a hard, gloss red finish. The polyester coating provides excellent corrosion and wear resistance.
Chemical Resistant
Resistant to dilute acids and alkalies, petroleum solvents, alcohols, greases and oils.
Weatherability
Resistant to humidity, water and ultraviolet radiation.
Abrasion and Impact Resistant

NYLON 11 COATING

Nylon 11 has superior corrosion resistance and has been used successfully in many applications such as water, cement, food and seawater.

Weatherability

Bray’s Nylon 11 coating has been salt spray tested in excess of 2000 hours and used in seawater immersion service for over 30 years without any deterioration of the coating resulting in no corrosion to the coated metal components.

Abrasion and Impact Resistant

SEACORR® COATING

This proprietary coating for actuators provides superior product protection in corrosive conditions, tested to ASTM B-117
