Product details

Grooved butterfly valve is an efficient and energy-saving fluid control valve suitable for various pipeline systems. The valve adopts a slot connection method, providing a fast and reliable installation method, and is suitable for regulating and cutting off fluid flow in large and medium-sized pipeline systems. Its butterfly structure design makes the valve small in size and light in weight, and can provide efficient flow control under low pressure conditions.

Product Overview

This grooved butterfly valve is a lightweight, compact flow control valve designed for quick installation and reliable sealing. It features a concentric, bidirectional soft-seal design for bubble-tight shutoff and 90° quarter-turn operation. The grooved end connection enables fast, weld-free assembly and disassembly using standard couplings, saving time and labor. Ideal for fire protection, HVAC, and water distribution systems, it offers low torque operation, minimal pressure loss, and excellent vibration absorption.
