These valve types reflect Check-All ‘s design approach

Silent Check Valve

A silent check valve uses a spring-assisted poppet to close before flow reversal, helping prevent hydraulic shock, also known as water hammer.

Spring-Loaded Check Valve

A spring‑loaded check valve uses a spring to help the poppet close before flow reverses, preventing backflow and reducing hydraulic shock also known as water hammer.

Poppet Check Valve

A poppet check valve uses a disc at the end of a stem as the checking mechanism, often with a spring to assist closing before flow reverses.

Inline Check Valve

An inline check valve positions the checking mechanism directly in the fluid pathway and is often compact for easy installation and space‑constrained systems.
