Features
- Floating seat with O-ring seals for bidirectional sealing at approximately half the standard operating torque
- Dual PTFE and metal sealing: PTFE-to-metal and metal-to-metal seat sealing with debris-cleaning capability
- Grease injection port at seat enabling zero-leakage sealing
- Flow guiding holes in gate to protect sealing surfaces from media erosion
- Straight, smooth full-bore channel when fully open for low flow resistance and pipeline pigging capability
- Self-sealing packing structure with auxiliary grease injection for near-zero packing leakage
- Self-relieving seat that automatically releases trapped cavity pressure when valve is closed
- Fully enclosed, weather-resistant actuator suitable for all ambient conditions
- Open/closed position indicator
- Dual soft seal structure with multiple sealing rings
- Automatic self-cleaning mechanism removes deposits during operation
Notes
- Operator options listed as 'Manual, Electric, etc...' — additional actuator types available on enquiry
Description
A double disc gate valve manufactured from high-strength, high-temperature resistant materials, specifically designed for handling cracked gases in the petrochemical industry. The valve incorporates a slab gate design providing a straight, unobstructed flow path, dual PTFE and metal seating, and an automatic self-cleaning mechanism. It is suitable for high-temperature and corrosive media applications across a wide pressure and temperature range.
