Explosion-Proof Electric Ultra-Short Ball Valve
Automated quarter-turn valve for explosive atmospheres. Stainless steel or WCB body with PTFE/PPL seats delivers bubble-tight, corrosion-resistant shutoff. Explosion-certified electric actuator enables fast quarter-turn or modulating control. For oil & gas, chemical, pharmaceutical, and wastewater service.
Features
- Compact, lightweight design for quick, space-saving installation.
- Functions as on/off isolation or modulating control across a wide range of media.
- PTFE/PPL seat inserts provide self-lubricating, low-friction sealing that extends service life.
- Rotating, non-rising stem keeps packing stable; sealing tightens as line pressure rises.
- Blowout-proof, bottom-entry stem with shoulder retention; fire-safe metal-to-metal seal if the seat is compromised.
- Anti-static design: springs between ball, stem, and body dissipate static charges during operation.
- Handles oil, water, gas, slurry, pulp, and fibrous media across chemical, power, metallurgy, and light-industry service.
