Electric HP Butterfly Valve (SUS304, 10K)
Model: PAVE-15
PAVE-15 is an electric high-performance butterfly valve featuring a double-offset construction with a SUS304 body and disc and an RTFE seat. It supports a wide lineup from compact 20A and 25A sizes up to large bores, and is used for remote automatic shutoff and sequence-control lines in the chemical, plant, water/wastewater, and construction sectors.
Features

- High tightness and durability
- Double-eccentric structure with low torque
- ISO5211 Direct Mounting Pad applied
- For powder fluids or operating temperatures over 120°C
- Seat: RTFE (usable up to 220°C); METAL for higher temperatures
Frequently Asked Questions
- How does double-offset structure differ from standard CONCENTRIC structure?
- CONCENTRIC structure has the stem axis aligned with the pipe centerline as a standard form. Double-offset structure has the stem axis offset in two directions, so the disc and seat contact only at the moment of opening/closing and move in non-contact state during the middle rotation section. This reduces seat wear, extending life and lowering operating torque.
- What is the operating temperature of RTFE seats and the criteria for switching to metal seats?
- RTFE seats can be used up to approximately 220°C. For higher-temperature lines, sections in direct steam contact, or environments where soft seats cannot ensure long-term durability such as highly abrasive slurry or solid-laden fluids, the specification can be changed to metal seats.
- Can it be applied to small-diameter lines?
- High-performance butterfly valves are generally supplied for medium and large-diameter lines, but PAVE-15 has a lineup down to small sizes such as 20A (3/4 inch) and 25A (1 inch). It can be used as an alternative for small-diameter branch lines requiring short face-to-face length, fast operation, and low operating torque.
- What options can be added to electric actuators?
- Various options are available depending on application. Small-diameter valves have approximately 1-second high-speed open/close specifications available for lines requiring fast ON/OFF repetition, continuous flow control sections can use 4-20 mA proportional control specifications, and explosion-proof actuator specifications are available for areas handling flammable gas or ignitable liquids.
