Zero static valves are multi-port diaphragm valves used to prevent a stagnated flow by facilitating drainage. These valves offer an exhaust or purge passage for trapped items. Manufacturers also use the third port to sample or redirect process materials. Today, one of the most important types of valves used in the biopharmaceutical sector is the zero static “T” point-of-use valve. Point-of-use valves enable the transfer, sample, drain, or divert process fluids while minimizing the impact on vital systems like the Water for Injection (WFI) and Purified Water systems (PW).

Zero static valves can handle liquid, gaseous, or semi-solid streams without leakage or stagnation. Other valve designs that use reciprocating rods, balls, or flanges produce several exposed recesses where material builds up. As these buildups stagnate, they can produce bacterial growth that degrades pipework and pollutes the entire flow if it is not immediately removed.
Zero static diaphragm Valves Operation Principle
A diaphragm uses force to open, close, or operate a valve. It is a flexible, pressure-responsive element. The diaphragm contains a stud that connects it to the compressor. To start or increase the flow, the valve stem raises the compressor. Pressing the diaphragm against the bottom of the valve stops or delays fluid flow. Diaphragm valves are easy to install. Zero static diaphragm valves excel at controlling fluids with suspended solids. The diaphragm is the valve's gasket to stop leaks between the body and the bonnet cap.
Application Of Zero Static Valves
Zero static valves are used in biopharmaceutical, agriculture, irrigation, plumbing, water treatment, chemical and food processing, pulp & paper, mining, and energy production industries. They help guarantee the materials stay uncontaminated and the equipment stays uncontaminated from stagnant buildups. Zero static valve components are used in sanitary diaphragm, biotech, and hygienic valves.
Zero static valves can process silicones, adhesives, oils, chemicals, water, food, cleansers, sanitizers, coatings, and fuel. Therefore, valve component materials must be chemically compatible to maximize product longevity and efficiency. The materials utilized to build valve components include strong metals like brass, steel, and stainless steel, as well as PVC, CPVC, polypropylene, and other plastics.
Advantages of Zero Static Valves
- The distinctive diaphragm design of zero static valves allows for self-emptying capabilities.
- Zero static valves are simple to use, with minimal maintenance.
- Zero static valves will often have a sanitary surface finish.
- They are compatible with manual handles, pneumatic actuators, and electric actuators.
- Zero static valves are important for transferring, sampling, draining, and diverting process fluids in the biopharmaceutical sector.
Disadvantages of Zero Static Valves
- It’s advised to only use zero static valves at temperatures between -60 and 450o F.
- They must be built of corrosion-resistant materials.
Zero static valves are referred to as downstream purge valves or point-of-use valves. Therefore, it's critical to be informed of product specs to ensure the best valve is selected. When choosing a zero static valve, it is important to consider the following factors in addition to the material considerations described above: operating temperatures, production techniques, port number and size, overall dimensions, flow compensation, and actuator type. Zero static valves are a good solution when orientation, space restrictions, or drainage limits impact material flow.
Selecting the Proper Zero Static Valve Company
To ensure you have the most productive outcome when purchasing zero static valves from a zero static valve supplier, it is important to compare several suppliers using our directory of zero static valve companies. Each zero static valve company has a business profile page highlighting their areas of experience and capabilities, along with a contact form to directly communicate with the supplier for more information or request a quote. Review each business using our patented website previewer for an idea of what each company specializes in. Then, use our simple RFQ form to contact multiple zero static valve businesses with the same form.
