Main Features：
The double offset design of the SHENGFEI High Performance Butterfly Valves assures reduced seat wear and bidirectional, zero leakage shut off throughout the full pressure range. At the initial point of disc opening, the offset disc produces a cam–like action, pulling the disc from the seat. This cam–like action reduces seat wear and eliminates seat deformation when the disc is in the open position. When open, the disc does not contact the seat, therefore seat service life is extended and operating torques are reduced. As the valve closes, the cam–like action converts the rotary motion of the disc to a linear type motion to effectively push the disc onto the seat. The wiping action of the disc against the seat prevents undesirable material build-up from slurry or suspended solids.
Soft Seat High Performance Butterfly Valve
Product Overview:
The RPTFE soft seat provides a bi-directional bubble tight shutoff (zero leakage). The unique seat design creates a self-energized seal in vacuum-to-low pressure applications. Under higher pressure conditions, the seat is also designed to permit, confine, and direct movement of the soft seat against the disc edge.
Advantages:
Advantages of Soft Seat High Performance Butterfly Valve
- Excellent sealing performance
- High-temperature and corrosion resistance
- Easy to install
- Low maintenance cost
Metal Seat High Performance Butterfly Valve
Product Overview:
Metal seat high performance butterfly valves by its dynamic and flexible design, applies enough force per linear inch against the disc edge (Rock-well Hardness of C66 to C70) to obtain an optimum sealing characteristic while controlling the loads between the metal surfaces. metal seat is for higher tensile strength, utilized for temperatures up to 900°F, (482°C). The wear-resistant metal seat provides industry leading low torque. Bi-directional Leakage is rated at Class V.
Components of Metal Seat High Performance Butterfly Valve
Advantages:
Advantages of Metal Seat High Performance Butterfly Valve
- Wear and corrosion resistant
- Good mechanical properties
- Long service life
- Suitable for high temperature and high pressure
Fire Safe Seat High Performance Butterfly Valve
Product Overview:
The fire safe design incorporates two patented seats which function together to seal off pipeline flow. In normal operation, the soft seat provides a bi-directional “bubble tight” shutoff (zero leakage); the metal seat provides bi-directional shutoff in the event of a fire.in conformance to industry fire-safe requirements. With little or no pressure, the Fire-Safe seat creates a self-energized seal against the disc. Higher line pressures act on the geometry of both seats to dynamically load them against the disc, creating higher sealing forces in two ways.
The Fire-Safe metal seat is made of 316L material which is shaped by a proprietary hydroforming process into its unique, patented design. Stainless steel outer bearings are included for post-fire disc and shaft alignment. Graphite Fireproof packing is used to prevent external shaft leakage. Seat replacement is a simple operation, requiring no special tools.
