How Non Slam Disc Check Valves Work
Non slam disc check valves are automatic valves designed to allow fluid flow in one direction only, preventing reverse flow without any manual operation. The core mechanism consists of a spring-loaded disc housed inside a compact valve body.
When fluid flows in the forward direction, inlet pressure pushes the disc against the spring force, opening the flow path and allowing smooth passage of fluid. The spring is calibrated to offer minimal resistance to forward flow, ensuring low pressure drop during normal operation.
When flow velocity decreases or the pump stops, the spring mechanism begins closing the disc before reverse flow can develop. This pre-emptive closing action — happening before the fluid actually reverses — is what prevents the sudden slam and pressure surge known as water hammer. The disc closes gently and completely, achieving bubble-tight shut-off without noise or vibration.
This automatic, spring-assisted operation means non slam disc check valves require no actuators, no manual intervention, and virtually no maintenance during their service life. As a trusted Non Slam Disc Check Valve Manufacturer in Mumbai, Concorde Valves & Automations engineers every valve for consistent spring calibration and precise disc seat alignment to ensure reliable performance across thousands of operating cycles.

Frequently Asked Questions
Answers to common questions about non slam disc check valves, materials, sizing and selection.
A Non Slam Disc Check Valve is an automatic backflow prevention valve that uses a spring-loaded disc to allow fluid flow in one direction only. Unlike conventional swing check valves, the spring mechanism closes the disc rapidly before flow reversal builds up, preventing the slamming action and water hammer that cause pipeline damage.
Non Slam Disc Check Valves are used in oil & gas pipelines, water treatment plants, compressed air systems, chemical processing plants, fire fighting systems, HVAC systems, and industrial pump and compressor discharge lines — anywhere where backflow prevention and water hammer elimination are required.
The valve body is manufactured from ASTM A351 CF8 (SS304 equivalent) or CF8M (SS316 equivalent). Internal components including the disc, spring, spring retainer, and valve pin are made from AISI 304 or AISI 316 stainless steel. The O-ring seal is Viton for chemical and temperature resistance.
Concorde Valves & Automations supplies Non Slam Disc Check Valves from ½" to 2" in screwed (Female BSP / NPT) end connections as standard. Larger sizes and flanged end configurations are available on request.
Our Non Slam Disc Check Valves are rated to PN 40 and 3000 PSI with bubble-tight leakage test certification. Higher pressure ratings are available in special material grades.
Valves are available compatible with BS 10 Table D, E & H, DIN PN 6/10/16/25/40, and JIS 5/10/16/20 standards to match most industrial piping systems globally.
Standard construction uses a metal-to-metal disc seat for high durability and temperature resistance. Soft-seat options with PTFE or Viton inserts are available for applications requiring enhanced sealing at lower pressures.
Yes. Concorde Valves & Automations offers customization in body material (Duplex, Hastelloy, Carbon Steel), end connections, pressure ratings, size ranges, and seat material. We also provide third-party inspection, IBR certification, and material test certificates as per project requirements.
