Worcester 8716122007 SIT Gas Valve – Pre-Owned | Greenstar 8000 Life & Style

A Worcester Greenstar 8000 Life, Greenstar 8000 Style, Greenstar Life, Gr4700IW, or Worcester 2000 boiler that fails to fire, shuts down on a gas pressure fault, or displays a lockout error code often points to a gas valve that's worn internally, has a faulty solenoid, or has seized components. The Worcester SIT Gas Valve, Part No. 8716122007, is the genuine replacement that controls gas flow to the burner during every heating and hot water cycle, restoring safe and reliable operation.

This is a pre-owned valve, removed from a working or decommissioned appliance and tested before dispatch — a cost-effective alternative to buying new, particularly for older boilers where repair cost needs to be weighed against full replacement. SIT is the OEM valve supplier to Worcester Bosch.

Compatible Boiler Ranges

This is a high-fitment part across 50+ Worcester models — always verify compatibility using your boiler's full model number and GC number before purchasing.

Tested Before Dispatch. Cost-Effective Alternative.

This pre-owned 8716122007 valve has been checked and tested wherever possible before dispatch, restoring reliable gas flow control where a faulty valve was causing no-heat, no-ignition, gas lockout, or low pressure symptoms.
