Stainless Steel Disc Lug Type 4" inch butterfly valve

Stainless Steel Disc Lug Type 4 inch butterfly valve

LTD71X lug-type 4 inch butterfly valve can be driven by manual, worm gear, pneumatic or electric. The structure is centerline type, and the sealing structure is soft seal. It has a simple structure, small size and light weight, and consists of only a few parts.

It only needs to be rotated 90° to open and close quickly, which is simple to operate. At the same time, the valve has good fluid control characteristics. When the butterfly valve is in the fully open position, the thickness of the butterfly plate is the only resistance when the medium flows through the valve body. Therefore, the pressure drop generated by the valve is very small, so it has good flow control characteristics.

The products are widely used for regulating and intercepting pipelines in water treatment, shipbuilding, chemical industry, petrochemical, smelting, medicine and food industries.

About Butterfly Valve

Butterfly valve is a disc mounted on a rotating shaft. When completely shut down, the disk will completely block the circuit. When fully opened, the disc is at right angles to the air or liquid flow. The advantage of a butterfly valve is that it is relatively cheap to manufacture and maintain. They are the most common valves in large capacity water supply systems such as urban waterworks. They can be used for dirty liquid applications such as sewage or river water control. When the butterfly valve is fully opened, the butterfly disc is still in the flow line of the valve, so there is always a pressure drop on the butterfly valve. In addition, if the differential pressure on the butterfly valve is large, it may be difficult to open the valve. Some applications require a bypass valve to reduce the pressure differential before large butterfly valves can operate.

Frequently Asked Questions

As the name suggests, Normally Open valves allow air to pass when they are not energized (or actuated). Normally Closed valves must be actuated to allow air to pass.
We have passed 1 million times of product quality test, and obtained the certificate.
The air actuator does not have a manual override, but a manual override is provided with optional direct mount solenoid valves.
See product specifications. Generally, smaller valves less than 2 inch pipe size, cycle in about one second. Larger valves up to 6 inch pipe, cycle in about 1.5 seconds. A cycle is per 90° rotation
