[LMV1001] APEX Pressure Limiting Stop Valve

APEX Pressure Limiting Valve – LSV-20 Series

The APEX Pressure Limiting Stop Valve (LSV-20 Series) is a compact, high-performance 4-in-1 plumbing control valve designed to provide pressure limiting, isolation, non-return protection, and filtration in a single unit. Manufactured by APEX, a trusted and proven brand, it delivers exceptional reliability, efficiency, and long-term performance for modern plumbing systems.

Engineered with a forged, high-quality corrosion-resistant DR brass body, this valve is built for durability and consistent operation in demanding residential and commercial installations. It is designed to maintain a stable outlet pressure regardless of fluctuations in inlet pressure, ensuring safe and controlled water delivery.

The integrated stainless steel 250 micron filter helps protect plumbing systems by removing debris and particles, while the built-in isolation and non-return functions enhance system safety and performance.

With a factory pressure setting of 500kPa, the valve also delivers high flow rates up to 74 L/min, making it suitable for high-demand applications. The cartridge-based design allows for tool-free servicing, with all valve seats and piston components contained within a replaceable cartridge—ensuring maintenance is fast and simple without affecting set pressure.
