Sanitary Butterfly Valves
Sanitary butterfly valve is also called as hygienic butterfly valve
which is a type of flow control device, used to make a fluid start
or stop flowing through a section of pipe.
Sanitary butterfly valves uses:
Donjoy sanitary butterfly valves are widely used to the chemical
industry, petroleum, metallurgy, plumbing, food, bio-pharmaceutical
and chemical industries；Donjoy stainless steel butterfly valve,
sanitary fittings are high-quality products, can be used for dairy,
pharmaceutical, beer, beverage, edible oil and other industries to
meet their professional requirements.
Donjoy sanitary butterfly valves advantages:
Donjoy sanitary butterfly valve has many advantages such as
removable connection, simple structure and easy maintenance;
Donjoy butterfly valve rubber seals and valve plates are high
quality pieces to ensure the use performance and service
life;Donjoy valves can provide valve body and disc materials such
as AISI 304 or AISI 316L, 304Land 316 materials, automated or
manual operation valve according to your requests.
Application:
DONJOY is sanitary pneumatic butterfly valve actuator with
butt-weld ends, which is widely used in process piping systems for
isolation and control. butterfly valve operates automatically.
