Lug Butterfly Valve with Worm Gear

Product Details

The lug butterfly valve, which has lugs that allow it to be bolted onto the flanges and provide a secure connection, is appropriate for applications where the valve must be installed between two flanges. On the other hand, the wafer butterfly valve, which has a wafer that allows it to be sandwiched between the pipes and provide a tight seal, is appropriate for applications where the valve must be installed between two pipes.

Wafer-type butterfly valves typically come with the lowest price tag among the various connection methods. Lug-type valves are next in line, while flange-type valves are the most costly, with price generally correlating to overall weight.

Key Features

Standard Test

Valve body test: This test is conducted after the valve assembly is completed and the valve disc is in the half-open position. The test pressure is 1.5 times the working pressure, and water is used. It is also known as the valve body hydrostatic test.

Seat Ring Test: This test is conducted with water at 1.1 times the working pressure.

Functional/Operational Testing: During the final inspection, each valve and its actuator (flow control lever/gear/pneumatic actuator) will undergo a comprehensive operational test (opening/closing). This test is conducted under no-pressure and ambient temperature conditions to ensure proper functioning of the valve/actuator components (including solenoid valves, limit switches, and accessories such as air filter regulators).

Special Testing: Additional testing can be performed according to the customer’s specific instructions.
