About Series "W" Solenoid Valves
Granzow's Series W pilot operated solenoid valves are utilized for applications which require high flow rates. These valves are available with brass bodies, pipe sizes from 3/8" to 3", and sealing materials including Buna, FKM, or EPDM. Interchangeable coils offered for this series cover a wide range of AC and DC voltages. Connectors such as cable grip, ½" NPT conduit or power cords are available as well.
This particular solenoid valve series is provided with a manual override and adjustable closing speeds for the minimization of water hammer. In addition, the Series W solenoid valves are available with fixed closing speeds, lead free brass bodies with NSF61-G for potable water or NSF169 certifications, and normally open operation.
All Granzow solenoid valves are produced in an ISO 9001:2015 certified facility and are 100% tested before shipping.

Water Treatment and Filtration – Series W solenoid valves are very popular for emergency shutoff and inlet feed valves on water treatment applications. Considering the high flow rates and ability to have adjustable closing speeds, these features ensure a high performance valve which will have a very high degree of reliability versus competitive offerings.
Boilers and Water Heaters – Manufacturers of boilers and water heaters frequently utilize Granzow Series W valves for inlet feed or low pressure steam control. The W series valves can be equipped with EPDM sealing material which is suitable for low pressure steam.
Aquatics – Highly preferred solenoid valves for fountains, splash pads, commercial swimming pools and waterpark attractions due to the balance between performance and pricing. FKM sealing material can be used for highly chlorinated water and Granzow does manufacture the valves with up to 3" NPT process connections.
Low Pressure Steam – Low pressure steam applications require the use of sealing materials which can handle up to approximately 30 psi of steam (or head pressure). Considering EPDM sealants with Series W solenoid valves makes these valves a great option for low pressure steam control.
