Wafer Soft Seal Butterfly Valve uses the flexibility of rubber seat, could easily achieve zero leakage, Wafer type is the common style of butterfly valve and is less expensive than the lug type. The wafer butterfly valve is installed between two flanges. The valve is kept in place by using bolts or studs and nuts from flange to flange. This type of installation, of course, makes it impossible to disconnect just one side of the piping system from the valve. -
The lug type butterfly valve in ductile iron, Carbon steel or stainless is available with various seal options from Buna, EPDM, Teflon or Metal Faced. Handle or wheel options are available. Additional mounting of actuator limit switches Andy gear boxes are optional. A wafer butterfly valve’s function is to retain a seal to protect against dual-directional pressure differential in the flow of fluid. In other words, the wafer version of butterfly valves was designed to hold a tight seal, safeguarding against bi-directional pressure differential in order to avoid any backflow in systems that have been manufactured for uni-directional flow. This is accomplished by using a tightly fitted seal, such as an O-ring, gasket, precision machined, along with a flat valve face on the downstream and upstream sections of the valve. -

Electric ball valve is a high energy saving and long life product.It is mainly used for on-off control of HVAC water system,It is composed of electric driver and valve body.The driver (actuator) is driven by synchronous motor with stable action.When the valve is opened and the door is closed, the motor starts (electric power consumption 6W), Open valve or close valve action cycle time is 5-15 seconds,More than two line electric valve energy saving tens of times.(Because the electric ball valve only in the valve opening or closing state to work, the two-line electric ball valve opening motor has been energized). Therefore, the life of this product is several times that of the two-line electric valve. -

Features and Benefits: Manual brass ball valves are available in various sizes to meet a range of applications. They feature a manual hand lever and can be made from brass, stainless steel and plastic. Ball valves are popular as they are reliable and durable and still close securely over long periods making them suitable for shutoff and control applications.
