On-Center Resilient Seated Butterfly Valves Uninterrupted Seat Resilient Seated Butterfly Valves
In thousands of installations worldwide, DeZURIK BOS-US Uninterrupted Seat Resilient Seated Butterfly Valves have a proven record of long-term reliability and unmatched economy. These butterfly valves are ideally suited for a wide variety of liquids and gases, including water, air, petroleum, and noncorrosive chemicals. BOS-US Valves are extensively used in hot-process applications, in mining operations, in paper mills, and in environments requiring up to 28"-Hg (710mm-Hg) of vacuum. They provide bubble-tight, bi-directional shutoff to the full rating of the valve. They can be used in dead-end service without requiring downstream flanges. BOS-US Resilient Seated Butterfly Valves are an excellent choice for continuous modulating control or extended service applications, such as high cycle and higher pressures. Available is sizes 2 inches to 42 inches, BOS-US resilient seated butterfly valves can be used in services up to 250 degrees Fahrenheit.
DeZURIK BOS-CL On-Center Resilient Seated Butterfly Valves are used for a wide variety of liquids and gases in general service applications. These butterfly valves provide bi-directional shutoff to the full rating of the valve and can be used on dead end service with downstream flange attached. They feature superior bonded seats, heavy-duty bearings, multiple separate shaft seals, and a blow-out proof shaft. The On-Center Resilient Seated Butterfly Valve can handle pressures up to 175 psi (1210 kPa) in 2-12” sizes and to 150 psi (1030 kPa) in 14-48” sizes.
Tail Gas High Performance Butterfly Valves
DeZURIK BTG Tail Gas High Performance Butterfly Valves are specially designed to meet the rigorous requirements of services where polymerization or solidification of media can prevent valve operation. In addition to steam jacketing the body, Tail Gas Butterfly Valves also have internal steam passage ports located near the upper and lower body bearings to prevent media from solidifying. BTG Tail Gas Butterfly Valves are used for tail gas service in refinery sulfur recovery units, polymer processing or adhesive manufacturing.
