DeZURIK BHP High Performance Butterfly Valves are designed for demanding applications where standard resilient‑seated valves fall short. Used across chemical processing, pulp & paper, industrial water, HVAC, and municipal systems, BHP valves provide bi‑directional shutoff, precise throttling, and long‑term durability. Tek‑Sales frequently specifies BHP valves for systems requiring high velocity control, elevated temperatures, or stainless-steel construction.
FEATURES:
-
ASME Class 150 & 300 pressure classes
-
Wafer or lug body styles, 2"–60"
-
Offset disc design with one‑piece stainless steel shaft
-
Multiple seat options: PTFE, reinforced PTFE, metal, or dual seat
-
NSF/ANSI 61 & 372 certified for drinking water service
-
Fire‑tested options available for critical applications
BOS-US Uninterrupted Seat Resilient Seated Butterfly Valves are used to handle 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.
In thousands of installations worldwide, DeZURIK BOS-US Valves have a proven record of long-term reliability, throttling control, value-added design features and unmatched economy.
BOS-US valves feature an uninterrupted seat design, one-piece body, solid one-piece shaft and a high performance resilient seat. Sizes 2-20” (50-500mm) feature seat bonded to the body while sizes 24” (600mm) and larger feature a seat bonded to a solid backing ring.
FEATURES:
-
Uninterrupted Seat Design
-
Superior Bonded Seats
-
Bearings for Reliable Operation
-
Shaft Seals for Maximum Reliability
-
Blowout Proof Shaft
-
NSF-61/NSF-372 Certified
DeZURIK ON-CENTER RESILIENT SEATED BUTTERFLY VALVES (BOS-CL)
BOS-CL On-Center Resilient Seated Butterfly Valves are designed to handle a wide variety of liquids and gases. They are available in lugged 2-24" (50-600mm) ductile Iron body design with discs of nylon coated ductile iron, 316 stainless steel or aluminum bronze. BOS-CL valves feature a one-piece body, high performance seat bonded to a solid backing ring, three heavy duty bearings, and a blow-out proof shaft.
On-Center Seat design provides a streamlined disc with high flow capacity. Designed for both on-off and throttling, the BOS-CL provides bi-directional shutoff to the full rating of the valve. BOS-CL Valves provide bubble tight shutoff, and can be used on dead end service with downstream flange attached. For high strength and corrosion resistance, three disc material choices are available: Ductile Iron Nylon Coated, 316 Stainless Steel and Aluminum Bronze.
The BOS-CL seat bonding process ensures the seat is held firmly in place and provides a long lasting, maintenance free seal. The seat is bonded to a rigid backing ring which reduces flexing and fatigue
DeZURIK TAIL GAS HIGH PERFORMANCE BUTTERFLY VALVE (BTG)

DeZURIK has specially designed the BTG Tail Gas High Performance Butterfly Valve to meet the rigorous requirements of services where polymerization or solidification of media can prevent valve operation. BTG Tail Gas Butterfly Valves are used for tail gas service in refinery sulfur recovery units, polymer processing or adhesive manufacturing.
DeZURIK standard BHP High Performance Butterfly Valves are available with standard steam jackets for less rigorous requirements, but BTG Tail Gas Valves include unique features which keep the valve at process temperature and protect critical bearing and seat areas. In addition to steam jacketing the body, internal steam passage ports are located near the upper and lower body bearings. These features prevent hydrogen sulfide and other media from solidifying, freezing the bearings, damaging the seat and preventing tight shutoff.
