Specifications
Butterfly valve is a quarter-turn valve that used to start, stop, and regulate flow in pipeline system. It has a disc which is mounted on a shaft. By turning the handle in quarter turn, the disc will turn to open position or close position. When the valve is turn to open position, the disc move away from the seat and is parallel to the flow. In the close position, the disc is perpendicular to the flow and sealed by the seat. Partial rotation of handle is applicable for throttle application. It is design and manufacture according to API 609 standard. Inspection and testing had been carried out according to API 598 standard. Butterfly valve is widely installed on solid liquids application such as oil and chemical, water supply, fire protection, and wastewater treatment at low pressure.
Material and Design
Butterfly valve is available in cast iron material, which relatively result in low cost with standard performance. A blue color external paint had been applied on valve body to enhance the corrosion resistance. The seat is available in EPDM material which fit on the disk edge to provide sealing to any leakage.
Butterfly valve is made in wafer type design. For wafer type butterfly valve, it is in short body length and flange hole outside of valve body. The valve can choose to have flange holes on the outside of the valve body. The pipe flange is connected by a long bolt that runs through the entire valve body, and the seal between the valve and the pipe flange is realized by the gaskets on both sides of the valve, the flat valve and the O-ring surface.
Connection Type
For wafer type butterfly valve, it is installed between two flange with long bolts cross by and tighten with nuts. The pipe flange is connected by a long bolt that runs through the entire valve body, and the seal between the valve and the pipe flange is realized by the gaskets on both sides of the valve, the flat valve and the O-ring surface.

Frequently Asked Questions
What is the size range of ANSI 150# cast iron wafer type butterfly valves?
The size range of the ANSI 150# Cast Iron Wafer Type Butterfly Valves is from 1 1/2 inches to 6 inches.
What is the working pressure of ANSI 150# cast iron wafer type butterfly valves?
The working pressure that ANSI 150# Cast Iron Wafer Type Butterfly Valves can withstand is 150 PSI.
What is the function of ANSI 150# cast iron wafer type butterfly valves?
ANSI 150# Cast Iron Wafer Type Butterfly Valves are used to regulate or isolate the flow in a system which able to start, stop or restrict the flow in a system pipeline.
What are the types of ANSI 150# cast iron wafer type butterfly valves available?
Wafer Type.
How to differentiate wafer type and lug type butterfly valves?
A wafer type is the most typical and cost-effective type and it is sandwiched between two pipe flanges. This valve has the choice of having flange holes outside of the valve body. A lug type has threaded inserts outside both sides of the valve body. Lug type valves are recommended for use in dead end service since they have a lower operating pressure rating.
What is the working temperature range of ANSI 150# cast iron wafer type butterfly valves?
The working temperature range of ANSI 150# Cast Iron Wafer Type Butterfly Valves is from -30°C to 120°C.
