Adjustable, replaceable seats and solid disc construction on 24"–144" sizes
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
Engineered for long-lasting performance in the most demanding flow control environments, the DeZURIK BOS-US Uninterrupted Seat Resilient Seated Butterfly Valve is a trusted solution for municipal and industrial applications. Ideal for water, air, petroleum, and non-corrosive chemicals, BOS-US valves are extensively used in high-cycle, high-pressure, and high-temperature systems such as paper mills, mining operations, and hot-process lines.
What sets this valve apart is its uninterrupted seat design, which ensures bidirectional bubble-tight shutoff and outstanding vacuum service performance (up to 28″Hg). The resilient seat - bonded either directly to the valve body (2-20") or to a solid backing ring (24"+) minimizes maintenance requirements while maximizing seal longevity. With robust shaft seals, blowout-proof construction, and multiple trim materials including nickel-plated ductile iron, 316 stainless steel, and aluminum bronze, the BOS-US valve delivers excellent throttling control with the reliability engineer's demand. Tek-Sales supports clients from sizing to specification helping you integrate BOS-US valves into your system with confidence and precision.
FEATURES:
-
One-piece valve body and shaft for structural integrity
-
High-performance EPDM or NBR seats
-
NSF-61/NSF-372 certified for drinking water safety
-
Lug or wafer body options available
-
Engineered for long-term vacuum and dead-end service
DeZURIK ON-CENTER RESILIENT SEATED BUTTERFLY VALVES (BOS-CL)
The DeZURIK BOS-CL Butterfly Valve is a versatile, on-center resilient seated valve designed for reliable shutoff and flow control across a wide range of clean or slightly contaminated liquids and gases. With a streamlined disc profile for high flow capacity, BOS-CL valves are well-suited for both throttling and on/off applications and are a smart choice for projects requiring bi-directional, bubble-tight shutoff, including dead-end service with an attached downstream flange. Built with a one-piece ductile iron body and a durable bonded seat on a rigid backing ring, the BOS-CL ensures excellent seat retention and longevity, even under vacuum or high-cycle conditions. Available in 2-24" sizes with lug body configurations and disc options including nylon-coated ductile iron, 316 stainless steel, and aluminum bronze, this valve is tailored for performance in general service pipelines and industrial systems.
At Tek-Sales, we help you select the right valve configuration based on flow rate, media characteristics, and installation conditions - ensuring optimal BOS-CL integration into your system.
FEATURES:
-
On-center resilient seat with bonded design
-
Superior seat retention in vacuum or viscous service
-
Multiple disc material options for corrosion resistance
-
Blowout-proof shaft and triple-bearing support
-
Integral flange seals (no flange gaskets required)
DeZURIK TAIL GAS HIGH PERFORMANCE BUTTERFLY VALVE (BTG)
Designed for some of the most extreme service conditions in process industries, the DeZURIK BTG Tail Gas High Performance Butterfly Valve is purpose-built for media prone to polymerization or solidification. This valve is engineered specifically for refinery sulfur recovery units, polymer processing, and adhesive manufacturing, where conventional valves may seize or leak due to crystallizing or sticky media.
To maintain operability in challenging environments, the BTG valve includes steam-jacketed bodies and internal steam passage ports near the upper and lower body bearings. These critical design elements keep both the seat and bearing areas at consistent process temperatures, reducing the risk of bearing freeze-up, seat damage, or shutoff failure. Whether you need guidance on thermal protection requirements or help matching actuator specifications, Tek-Sales is your go-to technical resource for selecting and deploying BTG butterfly valves with confidence.
