The Hydrant Pit Valve family meets all the requirements of the API/EI1584 specification (3rd edition) for 4” hydrant system components, including the latest specified breakaway and strength levels.
The lower valve assembly contains an isolation valve which will allow the removal and servicing of the upper valve assembly and the pilot valve while the pit valve is still installed on the hydrant. The upper section (API adapter) is now furnished with a replaceable part that contains the interface with the hydrant coupler. This minimizes replacement parts expense and allows for easy replacement of the wearing surfaces. There are two types: the one is flanged 4 inch ANSI 150lb and can be fitted with an adapter to 6 inch ANSI 150lb. The other is flanged 6 inch ANSI 150lb as standard.
Both valve types can be supplied with a lanyard operated pilot valve, an air operated pilot valve or a dual air/lanyard pilot valve. We also offer a pilotless pit valve, where the major operating part of the pilot valve is incorporated within a quick disconnect actuator located on the hydrant dispenser air hose (Remote Pilot Valve), which reduces maintenance costs. Lanyard, air or dual air/lanyard operated Remote Pilot Valves are available.
