What Does an Anti-Siphon Valve Do?
An anti-siphon valve helps prevent unintended chemical flow when the discharge arrangement could allow liquid to siphon through the metering pump. It is an important accessory for suitable chemical dosing installations.
CHEM-TECH Replacement Application
The manufacturer parts schedule lists 41624 as the standard PVC/CSPE anti-siphon valve. It is associated with the CHEM-TECH mechanical metering pump parts family.
PVC and Hypalon Construction
PVC provides the valve body construction, while CSPE/Hypalon identifies the sealing material. Confirm chemical resistance for the intended fluid and operating conditions.
Connection Identification
The published parts schedule identifies a 1/2-inch connection. A separate stocked-parts listing describes it as 1/2-inch OD. Verify the original fitting arrangement before installation.
Why Correct Valve Selection Matters
An anti-siphon valve should match the original pump application, connection size and wetted-material specification. It should not be substituted with a standard injection check valve without reviewing the system design.
Maintenance Considerations
Inspect the assembly for leakage, deposits and deteriorated sealing components. Isolate the chemical feed and relieve pressure before removal.
