Double Flanged Butterfly Valve

Bray’s Series 3A/3AH valves are a double flanged design which can be used for dead-end service. All Bray valves are tested to 110% of full pressure rating before shipment.

A major design advantage of Bray valve product lines is international compatibility. The same valve is compatible with most world flange standards – ASME Class 125/150, BS 10 Tables D and E, BS 4504 NP 10/16, DIN ND 10/16, AS 2129 and JIS10. In addition, the valves are designed to comply with ISO 5752 - Table 2 (short pattern) face-to-face and ISO 5211 actuator mounting flanges. Therefore, one valve design can be used in many different world markets.

Bray interchangeability and compatibility offers the best in uniformity of product line and low-cost performance in the industry today.

Nylon 11 Coating

A thermoplastic coating produced from a vegetable base and is USDA Approved, as well as, certified to ASME/NSF61 for water service. It is inert to fungus growth and mold, has excellent resistance to impact and provides a very low coefficient of friction.

Nylon 11 also has superior corrosion resistance and has been used successfully in many applications such as water, cement, food and seawater. Bray’s Nylon 11 coating has been salt spray tested in excess of 2000 hours and used in seawater immersion service for over 25 years without any deterioration of the coating resulting in no corrosion to the coated metal components. As a result, the use of Nylon 11 in seawater with elevated chloride levels between 30,000 - 40,000 ppm continues to increase.
