1-1/4" PVC In-Line Spring Check Valve
S12-012 | SKU 100027251
This 1-1/4" in-line spring check valve features PVC construction, EPDM seals, and a listed pressure rating of 150 PSI. Its spring-operated mechanism responds automatically to system flow and pressure conditions.
1-1/2" PVC In-Line Spring Check Valve
S12-015 | SKU 100027252
This 1-1/2" in-line spring check valve features PVC construction, EPDM seals, and a listed pressure rating of 150 PSI. The valve helps prevent reverse flow in compatible piping systems.
2" PVC In-Line Spring Check Valve
S12-020 | SKU 100027253
This 2" in-line spring check valve features PVC construction, EPDM seals, and a listed pressure rating of 150 PSI. The automatic check mechanism allows one-way flow without manual actuation.
Spring-Operated Check Mechanism
The internal spring assists closure when forward flow decreases or reverse pressure develops. Valve opening depends on the pressure differential across the check mechanism.
Reverse Flow Prevention
These check valves are designed to allow flow in one direction and resist flow in the opposite direction. They are not substitutes for positive shutoff valves where manual system isolation is required.
PVC Construction
PVC provides nonmetallic valve construction for compatible piping applications. Confirm the intended fluid, operating temperature, and system pressure before installation.
EPDM Seals
All five sizes use EPDM sealing components. Verify compatibility with the intended fluid, chemical concentration, temperature, and operating conditions.
150 PSI Pressure Rating
All five models have a listed pressure rating of 150 PSI. Review the manufacturer's documentation for temperature-related pressure limitations and other service restrictions.
In-Line Installation
The S12 series uses an in-line valve configuration. Install the valve in the manufacturer's specified flow direction and follow the applicable connection and orientation requirements.
Automatic Operation
Unlike a manual ball valve, a spring check valve responds automatically to changes in flow and differential pressure. No handle operation is required.

What is the 2" valve part number?
The 2" valve is S12-020, SKU 100027253.
How does an in-line spring check valve work?
Forward pressure opens the check mechanism when sufficient differential pressure is present. The spring assists closure when forward flow decreases or reverse pressure develops.
What is the purpose of a spring check valve?
A spring check valve allows flow in one direction and helps prevent reverse flow through the piping system.
Do these valves require manual operation?
No. These valves operate automatically in response to flow and pressure conditions.
Are these ball valves?
No. These are spring-operated check valves, not manual ball valves.
Are these the same as the S13 spring check foot valves?
No. These products belong to the S12 in-line spring check valve series, rather than the S13 in-line spring check foot valve series.
What material are these valves made from?
These valves feature PVC construction.
What type of seals do they use?
All five sizes use EPDM seals.
What is the pressure rating?
All five sizes have a listed pressure rating of 150 PSI. Review the manufacturer's specifications for service limitations.
Can these valves be installed in any direction?
Installation orientation and flow direction must follow the manufacturer's instructions. Confirm the permitted mounting positions before installation.
Are these suitable for chemical service?
Suitability depends on compatibility with PVC and EPDM, along with the fluid concentration, operating temperature, pressure, and other service conditions.
Can these valves replace a manual shutoff valve?
No. Spring check valves operate automatically and should not replace a positive shutoff valve when manual isolation is required.
Where can I find technical documentation?
The manufacturer's Valves Specification Sheet is available in the Product Resources & Support section above.
