The VMAL Grooved-End Butterfly Valve is a resilient-seated butterfly valve designed for flow isolation and control in piping systems where a grooved-end connection is required. The catalog identifies this model as a clamp-type grooved end butterfly valve, with a PN16 (200 PSI) working pressure rating.
With a compact butterfly valve design and grooved connection, the VMAL valve is suitable for a wide range of industrial and building-service applications, including HVAC, water supply and sewage, food and beverage, chemical and petrochemical processing, power and utilities, paper and pulp, and shipbuilding.
VMAL Grooved-End Butterfly Valve Design
The VMAL Grooved-End Butterfly Valve uses a resilient-seated eccentric butterfly valve construction. Its grooved-end configuration is designed for clamp-type pipe connections, providing a practical solution for piping systems that use grooved coupling technology.
The valve is available in nominal sizes from DN50 to DN300, corresponding to 2″ to 12″. The catalog provides dimensional data for each available size, including H1, H2, C, L and A/B dimensions.
The mounting flange follows ISO 5211, allowing the valve to be configured with compatible actuation equipment according to the specified mounting interface.
