Description

The Wingrou XD381X 4″ Butterfly Valve with Tamper Switch Grooved End is engineered to maintain safety integrity and ensure reliable flow monitoring across commercial sprinkler risers, standpipe systems, and industrial fire protection networks. Built with a high-strength ductile iron body and an EPDM-encapsulated disc, this 4-inch (DN100) grooved butterfly valve provides bubble-tight shutoff and low hydraulic head loss. The integrated gear operator features dual internal tamper switches that connect directly to a fire alarm control panel, providing instant electrical indication if the valve is partially closed or tampered with. Designed for quick installation using standard grooved mechanical couplings, its fusion-bonded epoxy coating ensures long-term resistance against internal and external corrosion.

Features

Built-in dual supervisory tamper switches allow seamless electrical integration with fire alarm panels to monitor valve closure
Precision grooved ends eliminate welding and flanging, significantly cutting pipe assembly time and labor costs
EPDM-encapsulated ductile iron disc provides bubble-tight shutoff with low operating torque and minimum pressure drop
Electrostatic fusion-bonded epoxy coating internally and externally protects against rust, pitting, and tuberculation
Clear visual position indicator on top of the gear operator provides instant field verification of open/closed valve status
