Wafer butterfly valves are commonly used to control the flow of fluids in various industrial and commercial systems. The dimensions and types of China wafer butterfly valve can vary to suit different system requirements.
Here are some of the ways the dimensions and types of wafer butterfly valves can vary:
Valve Size:
Wafer butterfly valves are available in a wide range of sizes, typically from 2 inches (50 mm) up to 48 inches (1200 mm) or even larger.
The valve size is selected based on the pipe size and the required flow capacity of the system.
Body Material:
Wafer butterfly valves can be made from different materials, such as cast iron, ductile iron, stainless steel, or various types of plastic (e.g., PVC, CPVC, polypropylene).
The choice of body material depends on the properties of the fluid being handled, the system pressure and temperature, and the required corrosion resistance.
Disc Material:
The disc, which is the rotating element of the valve, can be made from different materials, such as stainless steel, aluminum, or various types of plastic.
The disc material is selected based on the fluid properties and the required strength and durability.
Seat Material:
The seat is the part of the valve that seals against the disc to control the flow.
Seat materials can include rubber, PTFE (Teflon), or other specialized materials, depending on the application requirements.
Stem Material:
The stem is the shaft that connects the disc to the actuator or handle.
Stem materials can include stainless steel, brass, or other materials, depending on the system requirements.
Actuator Type:
Wafer butterfly valves can be manually operated, or they can be equipped with various types of actuators, such as electric, pneumatic, or hydraulic actuators.
The choice of actuator depends on the required level of automation, control, and torque requirements.
Pressure Rating:
Wafer butterfly valves are available in different pressure ratings, typically ranging from low-pressure (e.g., 150 psi or 1 MPa) to high-pressure (e.g., 600 psi or 4 MPa) designs.
The pressure rating is selected based on the system pressure and safety requirements.
By selecting the appropriate dimensions and types of wafer butterfly valves, system designers and engineers can ensure that the valve is suited to the specific requirements of the application, such as fluid properties, pressure, temperature, and flow rate.
