The ELK-WSV3 is a new and improved model of our highly popular electric water shutoff valve. It is designed for residential and light commercial domestic water applications.

From the time of activation the WSV3 can shut off the main water supply to a building in just under 1 second. The ELK-WSV3 features a 1” full bore stainless steel ball valve with commercial grade seats and seals. This valve does not restrict water flow and is safe for drinking water. The motorized actuator has a permanently lubricated gear drive with sufficient torque to open or close the valve under high pressure or after long periods of inactivity. The ELK-WSV3 can be operated via a SPDT (single pole, double throw) relay triggered from virtually any security or automation controller. It can also be operated using a simple SPDT latching push button.
