Description
High performance butterfly valve
The Wafer High Performance Butterfly Valve is an advanced valve designed for high performance and cost efficiency. The Wafer High Performance Butterfly Valve is a sophisticated piece of engineering that can provide a bubble-tight shut-off, making it one of the highest performing valves on the market for a variety of applications.
The innovative design of our Wafer High Performance Butterfly Valve incorporates a flexible-lip into a compact and lightweight body. This design is easy to operate, and ensures a tight shut-off of the highest quality.
The Wafer High Performance Butterfly Valve is suited to a number of different applications and is utilized in Airport Refueling, Hydrocarbon Processing, HVAC applications and other areas such as Air Treatment, Chemical Processing, Purified Gas distribution, Steam and Vacuum applications and many more.
The butterfly valve is designed with enhanced sealing and safety in mind, with use of Belleville washers and retaining ring to provide primary sealing between the shaft and packing, and to ensure blowout proofing.
Enhanced Valve Design Features:
- Streamlined one-piece stem design with ISO 5211 square drive
- Convenient direct mounting flange on valve body
- Easy-access gland packing adjustment with actuator in place
- Reliable primary sealing with Belleville washers on gland nut
- Retaining ring for secure packing pressure and stem protection
- Enhanced sealing options: RPTFE chevron for soft seat, Graphite chevron for fire safe and metallic seat
- Extended neck for insulation compatibility
- Pin-less shaft connection for easy maintenance and corrosion resistance
- Seat retainer for simple seat replacement
- Double offset disc reduces valve torque
- Hardened alloy disc surface for extended sealing life
- Integral disc stop to prevent over travel
- Interchangeable soft, fire safe, and metallic seats
- PTFE lined SS316 bearing for increased service life
- Thrust ring for anti-blowout and anti-static protection
