A WRAS butterfly valve is a rotary valve that uses a disc as the closure member. The disc shaped closure member is rotated through 90 or there about to open or close the passage. The disc of WRAS butterfly valve closes against a ring seal to close off the flow. The other main parts are the WRAS butterfly valve body, the stem/ shaft and the valve actuator.

WRAS butterfly valves are commonly used as a shutoff valve and flow control valves. As a shutoff valve, WRAS butterfly valve is to block the passage of fluid in its closed position and prevent any sort of leakages. Not only should WRAS butterfly valve efficiently seal the pipe and the flange to prevent internal leakages within the piping system, but also eliminate fugitive leakages escape from the valve to the atmosphere.

A WRAS butterfly valve is a rotary valve that uses a disc as the closure member. WRAS butterfly valve are the most specified valve type for moderate-duty conditions in pipe sizes of two inches and larger. WRAS butterfly valve’s reduced weight, reliable bubble-tight shut-off, ease of operation and automation allowed them to displace gate valves in traditional applications.

WRAS butterfly valves are throttling valves that turn in a quarter-turn rotary motion. WRAS butterfly valves control the media flow in a system. The operators use these WRAS butterfly valves in different media and applications. When you operate a WRAS butterfly valve, it has a similar principle to a ball valve, that allows a fast shut off.

Failures are the most common questions when it comes to issues on WRAS butterfly valves. We know how frustrating when you come across a problem, especially if WRAS butterfly valve is a newly purchased item and you’d expect the best from it. Don’t panic when this is your case, as some WRAS butterfly valve issues can be easily solved due to their simple geometry and design.

A WRAS butterfly valve is a type of quarter-turn valve that controls the flow of a product in a pipeline. From pharmaceuticals to manufacturing and food processing, the WRAS butterfly valve has a variety of applications and can be used to limit solid, liquid, or gas material flow. Two sets of bolts connect pipe flanges to each side of the bolt inserts without nuts. WRAS butterfly valves used in dead end service generally have a lower pressure rating.

WRAS butterfly valves can be less expensive to purchase and are easier to maintain, thereby resulting in lower maintenance costs. WRAS butterfly valves are fast-acting, being quarter-turn valves, which can open and close in less time than some other valve designs. WRAS butterfly valves generate small pressure drops. With suitable seats, WRAS butterfly valves can be used with chemicals and corrosive media. WRAS butterfly valves are narrow and take up less space in an installed setting, which are easy to install, save time and installation costs.

control fluid flow in a pipe by using a disc attached to a central shaft. This disc of WRAS butterfly valve controls the amount of fluid passing through the valve by creating a variable opening. Majority of WRAS butterfly valves with plastic linings are zero offset. Those that are made of metal and some with rubber lining are either PTFE lined butterfly valve or WRAS butterfly valves.
