LPF11 angle seat valve is a robust pneumatic quick control valve with an angle seat design that provides excellent flow, minimal pressure drop, and reliable leak free closure to achieve the required frequent switching control.
Product Description
Designed to optimize automated fluid control, LPF11 Pneumatic Angle Seat Valve features a durable stainless steel body and a self-adjusting PTFE seal that effectively handles high-temperature steam, viscous fluids, and media containing suspended solids. Its unique angled flow path significantly reduces turbulence and prevents clogging, providing a highly durable, maintenance-free alternative to traditional globe valves in challenging process environments.
Key Features
- Water Hammer Protection: Specially designed water hammer-proof models are available to absorb pressure surges and protect downstream piping systems from damage.
- Optimized Flow Path: The angled seat design minimizes flow resistance and prevents clogging, making it ideal for high-viscosity fluids and saturated steam.
- Leak-Tight Sealing: Equipped with a self-adjusting PTFE seal and a robust pneumatic actuator, it guarantees zero external leakage and tight shut-off over millions of cycles.
- High-Temperature Resistance: Constructed from durable SS304/SS316 stainless steel with premium sealing materials, it reliably handles aggressive chemicals and steam up to 180°C.
- Fast-Acting & Compact: The lightweight, space-saving actuator ensures rapid response times and precise flow regulation for automated process control.
- Versatile Installation: Supports both co-current (flow-under-seat) and counter-current (flow-over-seat) configurations to adapt to varying pipeline pressure requirements.
Typical Applications
- Steam & Thermal Systems: High-temperature steam control, sterilization equipment, and boiler feedwater systems.
- Water Treatment & Beverage: Ultra-pure water regulation, chemical dosing, and CIP (Clean-In-Place) processes.
- Chemical & Pharmaceutical Processing: Safe isolation and control of corrosive liquids, organic solvents, and semi-fluids.
- Textile & Paper Manufacturing: Precise throttling and shut-off for dyes, sizing agents, and high-viscosity pastes.
