The valve is typically placed in a cylindrical body, and the disc is connected to a handle or actuator that allows for easy operation.
Butterfly valve shutoffs are known for their low-pressure drop and high flow capacity. They are often used in applications where a high flow rate is required, and the valve needs to be opened and closed frequently. However, they can be prone to wear and tear due to the high friction forces involved in their operation.
Globe Valve Shutoff
Globe valve shutoffs are used in washing machines where precise control of water flow is required. They consist of a cylindrical body with a round or oval-shaped valve disc that rotates to open or close the flow path. The disc is typically connected to a stem and handwheel or other actuator for easy operation.
Globe valve shutoffs offer precise control over water flow rates and are often used in washing machines with high water-pressure systems. They are also suitable for applications where a high degree of precision is required, such as in laboratory or medical equipment. However, they can be more complex and expensive than ball and butterfly valves.
