Butterfly Valves

Chemical plants, hydrocarbon processing facilities, pulp & paper mills, and industrial water and wastewater treatment facilities trust our butterfly valves for superior performance. DeZURIK BHP High Performance Butterfly Valves in ASME Class 150 and 300, provide exceptional performance while reducing the total cost of ownership. DeZURIK High Performance Butterfly Valves have been successfully applied in extreme services, including high-temperature services, throttling steam control, high-cycle industrial gas, and more. High Performance Butterfly Valves are available in sizes up to 60 inches and temperatures up to 700 degrees Fahrenheit. DeZURIK BHP High Performance Butterfly Valves are also ideally suited for critical applications in the water industry, where high pressures, high velocity flows and stainless steel construction are required. When specified, DeZURIK BHP Valves are certified to meet NSF/ANSI-61, 372 Drinking Water Systems Components – Lead Content which provides recognized safety in municipal water service. High Performance Butterfly Valves are available with manual actuators, all-stainless steel rotary diaphragm actuators, PowerRac cylinder actuators, and others.

DeZURIK BAW AWWA Butterfly Valves deliver results and meet stringent American Water Works Association C504 and C516 standards. AWWA Butterfly Valves can be applied in services demanding high-quality and thoroughly tested valves which offer many years of trouble-free service. DeZURIK BAW Butterfly Valves come in sizes ranging from 3 inches to 144 inches, with temperature ranges up to 290 degrees Fahrenheit and several pressure ratings. Designed with an offset disc, our AWWA Butterfly Valves feature corrosion-resistant shafts, stainless steel disc edges, and self-compensating shaft seals. The larger valves also have adjustable and replaceable seats and non-hollow disc structures.

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 (710 mm-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 in sizes 2 inches to 42 inches, BOS-US resilient-seated butterfly valves can be used in services up to 250 degrees Fahrenheit. BOS-US Butterfly Valves are available with manual actuators, PowerRac cylinder actuators, and others.

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 blowout-proof shaft. The On-Center Resilient Seated Butterfly Valve can handle pressures up to 175 psi (1210 kPa) in 2-12” sizes and up to 150 psi (1030 kPa) in 14-24” sizes. BOS-CL Butterfly Valves are available with manual actuators, PowerRac cylinder actuators, and others.

DeZURIK BTG Tail Gas High Performance Butterfly Valves are specially designed to meet the rigorous requirements of services where polymerization or solidification of the 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.
