Quiet check valves, also referred to as non-slam check valves and spring-assisted check valves, serve to diminish or eradicate water hammer and its repercussions.

Water hammer denotes the occurrence of high-pressure shock waves ensuing from the sudden cessation of fluid flow within a piping system, often due to pump shutdown or swift valve closure. This phenomenon imposes significant strain on the pipes, jeopardizing their structural integrity and leaving them susceptible to potential rupture and harm. Swing check valves, tilting disc check valves, and double door check valves, among others, frequently exacerbate water hammer issues.

To mitigate water hammer and reverse flow, the utilization of quiet check valves is advisable. These valves are engineered to employ a specially designed stainless steel spring mechanism that controls the closure of the valve disc before the onset of flow reversal when the fluid-moving source halts and the forward flow diminishes. This spring assistance ensures that the valve shuts without slamming, effectively eliminating water hammer occurrences.

Product Options

Our comprehensive range of spring-assisted check valves can be tailored to suit specific application requirements and are suitable for employment in both horizontal and vertical liquid, gas, or steam setups.

We offer a diverse selection of quiet check valves, including:

Flanged check valves
Wafer check valves
Threaded check valves
Vacuum breaker check valves
Restrictor check valves
Sanitary check valves
The wafer-style Model Axial Flow Check Valve is a silent check valve meticulously engineered to prevent water hammer and reverse flow. This lightweight and compact nozzle check valve conforms to API 594 Face-to-Face dimensions, facilitating easy fitting between mating flanges. It finds utility across a wide spectrum of applications and industries involving liquids, gases, and vapors.

Design Features & Advantages

Crafted with a singular objective of averting water hammer, our quiet check valves are globally acknowledged for their efficacy in forestalling reverse flow and water hammer-related issues. Furthermore, our quiet check valves commence opening at approximately 0.5 PSI differential pressure, achieving full opening at 1.0 PSI differential pressure.

Moreover, our quiet check valves boast the following attributes:

Fully compliant with MSS SP 126-2000 Steel In-Line Spring-Assisted Center Guided Check Valves Standards
Available with soft seats for leak-free sealing
Suitable for employment in liquid, gas, or steam applications
Facilitate smoother fluid flow and responsive opening and closing, obviating sudden movements responsible for water hammer
Applications

Our quiet check valves find favor in commercial and industrial domains, proving ideal for horizontal and vertical installations across liquid, gas, or steam applications.

Industries benefitting from our check valves encompass: Building maintenance, Chemical processing, Energy, Gas transmission, Government, Mining, Oil & Gas, Paper/pulp, Primary metals, Research/testing, Textiles, Water treatment
