Check Valves

The 3-piece in-line valves of our design, whether ball or piston, are made from forged bar. They are designed as forged union fittings.

​

The body/end seal is of the torus-on-cone type with a standard pressure class PN250.

 

A shutter return spring allows them to be mounted in all positions.

 

AS A REMINDER : A check valve is a device that automatically interrupts the flow of a fluid when its direction reverses.

​

Depending on the nature of the fluid and its state (liquid or gas), a choice of scope is necessary.

 

Depending on the waterproofing rate requested, a choice of range is necessary.

 

Depending on the mode of operation and the frequency of use of the valve, a technological choice is necessary.

 

A non-return valve is not a regulating device (regulator/reliever), nor a safety device (valve).

​

The SALVI Range

• Opening threshold: 0.2 bar (possibility of modifying the opening threshold depending on the model)

• Connection: Gas, NPT, SW, (BW possibility or flanges depending on model)

 

SALVI technology

• Body in forged 316L stainless steel

• Spring

• Cryogenic version

• Nuclear version

​

Commitment to SALVI valves

• Our check valves can be tailored based on your operating requirements and corrosion severity.

• Our non-return valves can be supplied with a certificate of conformity and material certificates.

• Our non-return valves can be modeled in 3D to be integrated into your plans.
