Globe Valves

LPF11 Angle Seat Valve

LPF11 Angle Seat Valve is a robust pneumatic control valve engineered with an angled seat design to deliver superior flow rates, minimal pressure drop, and reliable leak-tight shut-off for demanding industrial media.

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.
