Features
- High Temperature Media Handling: Ideal for hot or high-temperature process fluids.
- Minimal Contact Movement: Precision-ground gate held between gland packing reduces contact with body during most of its travel.
- Non-Sliding Gate Motion: Seating aided by body jams avoids sliding contact, improving durability with abrasive particles.
- Beveled Knife Edge: Bottom edge of the gate ensures positive closure even with settled solids.
- Deflection Cones & Hard-Faced Surfaces: Protect seat and body surfaces from direct impingement of abrasive media.
- Durable & Reliable: Engineered for long service life under challenging industrial conditions.
- Purge Connections: Body and chest purges allow cleaning with higher-pressure fluids to minimize wear during operation.
- Hopper Isolation Capability: Can cut through flowing powders and dislodge material from seating area
- Thermal Expansion Tolerance: Design accommodates differential thermal expansion without affecting functionality.
- Application-Specific Design: Engineered for handling non-clean and abrasive media efficiently.
Applications
- Industrial oil refinery processes
- Handling of water, steam, air, gas, and corrosive fluids
- Adaptable to a broad range of pressures and temperature conditions
