Check Valve
Axial No-slam Check Valves
No-slam check valves are silent in-line and specifically designed to automatically protect critical components from reverse flow as well as pressure transients.
OTOM offers a compact version of the No-slam check valve, providing the same reliability and
quality of the traditional No-slam valves, but with significant space and weight savings. Material selection is fully customizable to meet customers project specifications.
- Metal-seated with hardfacing on disk and seat.
- Powerful spring for ultra-fast closing action.
- Venturi pattern design.
- Minor friction between moving parts to eliminate any chance of jamming.
- Spring assisted and short stroke.
- No chattering effect to minimize pressure fluctuation during normal conditions.
- Low pressure drop.
- High dynamic response and zero reverse flow.
- Nozzle design for valves over NPS 20 for better flow regulation.
- Short pattern design with compact face-to-face option for weight and space savings.

Swing Check Valve
The swing check valve features a rocker and valve connection designed with a spherical structure. This unique design allows the valve a 360-degree range of motion, providing flexibility and ensuring precise alignment and compensation in its positioning.

Dual Plate Check Valve
A wafer check valve operates automatically, allowing fluid to flow in one direction. When fluid pressure is applied in the correct direction, it opens the valve flap. Conversely, if the fluid flows back, the pressure pushes the flap onto the valve seat, effectively stopping the flow.
- Size: 2”~40”
- Class: 150Lb~900Lb
- Connection: Double flange / Wafer / Lug
- Temperature: -60°C to +450°C
- Body: Carbon steel(WCB,LCB) / Stainless steel(CF8,CF8M) / Duplex stainless steel(4A,5A,6A)/ Aluminium bronze / Bronze
- Disc: F304 / F316 / C95800
- Spring: SS316 / Inconel 625
- Design: API 594 / BS 1868
- Face to face: ASME16.10
- Flange end: ASME B16.5 / ASME B16.47
- Test: API598
