What it is

The Coster GCR 840 is a 40 mm gas valve with a 230 V electrical supply, a normally closed (NC) configuration and manual reset. It controls gas flow in heating appliances and gas-fired equipment. Manual reset means the valve must be reset by hand after closing and does not reopen automatically.

Before you order

  • Confirm the existing valve matches the Coster GCR 840 specification: 40 mm, 230 V, NC and manual reset.
  • Check the electrical supply and wiring arrangement are suitable for a 230 V valve.
  • Verify the valve is suitable for the gas type and appliance category in use, using the manufacturer's documentation.
