What is a zero static valve?
By Matthew Harrington
What is a zero static valve?
Zero static valves, which are diaphragm valves, are capable of handling liquid, gaseous and even semi-solid process streams without the risk of leaking or stagnation. Valve components must be made out of chemically compatible materials in order to promote product longevity and efficiency.
Where are GEMU valves made?
Worldwide production GEMÜ manufactures its comprehensive range of products in six countries on three continents. Manufacturing sites are located in Germany, Switzerland, China, Brazil, France and the USA.
What is a ported diaphragm valve?
Ported valves provide access to the interior of the body at the lowest possible cross section of the valves inlet or outlet when the body is oriented at the optimal drain angle. This access port can be used for sampling, steam sterilization, purging or condensate drainage.
What is a diaphragm valve used for?
In simple terms, the main purpose of a diaphragm solenoid valve is to control the flow of liquids and gases. Diaphragm solenoid valves have a rubber diaphragm that moves up and down within the body of the valve, causing opening and closing against a hard seat.
What is a point of use valve?
Point of Use (Zero Static) are some of the most critical diaphragm valves utilized in the Biopharmaceutical industry. Use point valves allow process fluids to be transferred, sampled, drained or diverted with minimal impact on critical systems such as WFI and purified water.
What are the advantages of diaphragm valves?
Advantages of Diaphragm Valve
- Can be used as on-off and throttling service valves.
- Offer good chemical resistance due to a variety of linings available.
- Stem leakage is eliminated.
- Provides bubble-tight service.
- Does not have pockets to trap solids, slurries, and other impurities.
What are the 2 types of diaphragm valves?
There are two main designs of diaphragm valves in industry: the weir/saddle type diaphragm valve and the straight-through/full bore diaphragm valve. These valves function similarly but only differ in their body shape, diaphragm, and application.
What is weir type diaphragm valve?
Dia-Flo weir-type diaphragm valves are utilized to handle media which is corrosive, erosive, or contains solids which tend to clog other types of valves. The weir-style diaphragm valve is used effectively as a control valve or where manual throttling of a fluid is desired.
What is another name for diaphragm valve?
Diaphragm valves (or membrane valves) consists of a valve body with two or more ports, an elastomeric diaphragm, and a “weir or saddle” or seat upon which the diaphragm closes the valve.
Why do we use diaphragm valve?
