1. Hōʻikeʻike
A spring check valve (kaulana pū kekahi me ka puna wai i kauʻia) he mea unidirection, self-actuating valve that prevents reverse flow in piping systems.
Designed for precision and reliability, it uses a spring mechanism to maintain closure until the pressure from the upstream side overcomes a preset threshold—known as the ke kaomiʻana i ke kaomi.
In fluid control systems where backflow could damage equipment, contaminate products, or disrupt operations, spring check valves are essential.

Axial (Ind-line) E nānā i ka Bross Valve
Axial spring loaded check valves feature a centrally aligned spring and disc (a iʻole pPPPet) that moves directly along the flow axis.
When forward pressure exceeds the spring force, the disc lifts to allow flow. Upon pressure drop or flow reversal, the spring rapidly reseats the disc, ensuring quick shutoff with minimal pressure loss and virtually no water hammer.
E hoʻohana i nā hihia: High-frequency flow systems, nā mea kanu lāʻau lapaʻau, aerospace fuel systems, and clean gas lines where space and performance consistency are critical.
ʻO ka pahu pahu pōkole
In this design, a spherical ball is pressed against a conical or spherical seat by a spring. When the upstream pressure rises above the spring force, the ball is lifted from the seat, allowing flow.
This type is simple, kumukūʻai-maikaʻi, and particularly well-suited for systems that require vertical mounting or handle fluids with minor contaminants.
E hoʻohana i nā hihia: Potable water systems, irrigation lines, light slurry applications, and basic fluid control systems where low pressure drop and ease of installation are valued.
Piston-type spring loiloi
This valve uses a guided piston as the closing element, providing greater alignment and sealing precision.
The piston moves linearly against the spring, offering superior tight shutoff performance and minimizing the risk of leakage.
Its controlled motion makes it ideal for systems that require reliable backflow prevention under variable flow conditions.
E hoʻohana i nā hihia: Nā'ōnaehana Hydraulic, fuel injection lines, pressurized gas systems, and industrial automation circuits.
