Product Description

Application:
RF Hygiene SS 304 /316L Stainless Steel Welded Butterfly Type Ball Valve used in food, beverage, wine   is a kind of automatically or manually manipulation of butterfly type ball valve,because of it can be very good deal with viscous or medium with particulate,which is widely used in food,beverage,pharmaceutical and chemical industrial piping system,to regulate and control the medium flow in the system.

Operating Principle: 
RF Hygiene SS 304 /316L Stainless Steel Welded Butterfly Type Ball Valveused in food, beverage, wine  are a type of quarter-turn valve used to regulate the flow of a fluid. The valve mechanism requires a 90-degree turn to go from the fully open to the fully closed position. The basic butterfly valve has three primary components: A disc, a stem, and a seat.
The disc is a thin, typically circular, metal plate that opens or closes the valve. When the valve is opened, the disc is aligned parallel to the fluid flow, allowing unrestricted flow. When the valve is shut, the disc is perpendicular to the fluid movement, using its surface area to prevent flow through the pipe.
The stem is a shaft that transmits motion from the handle or actuator to the disc. In some applications, the stem may be combined with the handle or disc as a single component.
The valve seat seals the gap between the pipe flange and the valve disc to provide shut-off. The performance of butterfly valves is heavily dependent on the quality of the seat construction and its ability to seal.

Design Features: 
Free maintenance
Portable and compact
Small torquemoment
Valve body can be replaced in any connections,and the length will not change.
Handle can be installed on the side of the valve body,no matter of the flow direction.
It can match with pneumatic and electric actuators.
It can match with wash mouth.

The high- performance double-flanged butterfly valve series are the renewed products that are desighed and debeloped by the company's new product debelopment department according to the request of many clients. This kind of balbe can reach the up-to-date world adbanded lebel b adoptig the successful ecperiences obtained through the butterfly valve reseach since the half acentury tocreate the unique structure so as to gain high-quality performances, The calce, charactered, high pressure differentce, free and labor-saving actuating, is widely used for cutting off media floeing in the high and medium-pressure industrial pipeline for water supply, drainage, metallurgy, peteoleum chmicals, electric power. Feature of the high perfomance double flange butterfly Valve 1. The valve is equipped with eccentric tilting tapered valve seat sealing ring for the purpose if pressing out the sealing surface has small frictional resistance. When shutting off, it cleses more and more, so this makes sealing performance reliable, Opening can ensure that the sealing. 2. The special geometric structure makes the butterfly valve free of defect that other butterfly balves are unable to be sealed will due to excessively opening, so as to gurantee good sealing of the surface. 3. The double eccentric butterfly valve structure can gurantee that the valve fundtions mormally under high prssure and overcome the shortcomings that other valve easily leak due to sest deformation when they work under high pressure.
