Grooved End Butterfly Valve

The Grooved End Butterfly Valve is a specialized quarter-turn valve designed for fast, easy, and secure installation in grooved piping systems. It combines the excellent flow control characteristics of a butterfly valve with the material savings and installation convenience of grooved couplings.

🌟 Product Purpose and Advantages

The Grooved End Butterfly Valve is primarily used for regulating and isolating fluid flow in large-scale piping systems across various sectors.

Advantage	Detail	Impact
Excellent Flow Control	When fully open, the butterfly disc’s thickness is the only resistance to flow.	Minimal Pressure Drop: Results in excellent flow control characteristics and lower energy loss across the valve.
Material & Cost Efficiency	Connects to the pipeline using grooved couplings (clamps) on both ends.	Resource Savings: Significantly reduces the material required compared to flanged or wafer-style connections, supporting energy-saving and emission-reduction policies.
Ease of Installation	Uses a simple mechanical clamp connection.	Fast, Reliable Installation: Installation is quick, convenient, secure, and highly reliable, reducing labor costs and construction time.
Versatile Application	Wide use in systems transporting various fluids.	Broad Suitability: Ideal for plumbing, fire protection, HVAC, water treatment, shipbuilding, and general municipal pipeline engineering.

🛠️ Installation and Maintenance Guidelines

Proper installation is crucial to ensure the valve’s reliability and longevity.

Handling Caution: The actuator structure (turbine, handwheel, or lever) must never be used for lifting the valve. Avoid all collisions or impacts during transportation and handling.
Mounting Orientation: The valve is typically installed vertically, meaning the valve stem should be in a vertical position with the handwheel or actuator positioned on top.
Bypass Valve Use: If the valve assembly includes a bypass line, the bypass valve must be opened first before operating the main butterfly valve.
Lubrication Schedule: For valves used frequently, cleaning and lubrication should be performed at least once per month to ensure smooth operation and prevent seizing.
Actuator Installation: If the valve is equipped with an actuator (electric or pneumatic), the mounting and installation procedure must strictly follow the instructions provided in the operation manual.
Connection Integrity: Connecting components (grooved couplings) must be tight and secure. The valve’s final installation position and height must conform to the project’s design standards.
