Techcon Systems, Inc.
Diaphragm Valve Diaphragm Valves are designed to dispense low to medium viscosity materials with precision accuracy over a wide range of shot and bead sized down to a fraction of a micro liter. An internal spring return makes the valves fully adaptable for use with Techcon Systems time/pressure controllers. A short opening stroke provides extremely fast, positive shut-off. An external stroke control adjustment makes it easy for the operator to fine tune shot sizes. The compact design allows for mounting...

Valcor Engineering Corporation
Custom Diaphragm Valves Valcor Engineering Corporation manufactures custom diaphragm valves to match your specifications. Our Diaphragm Isolated Solenoid Valves employs flexible diaphragms or bellows that isolate the valve's operating parts from the fluid being handled. No metal-to-fluid contact is permitted. Because of their construction, Valcor's Isolated Solenoid Valves are not subject to the major problems which often causes ordinary "wetted" solenoid valves to fail. Our diaphragm-isolated valves offer... (read more)Browse Diaphragm Valves Datasheets for Valcor Engineering Corporation
Diaphragm Valves for Hot Acids Tantaline treated acid resistant diaphragm valves offer the most corrosion resistance commercially available at prices 15% - 20% less than Hastelloy diaphragm valves. Tantaline treated acid resistant diaphragm valves are designed for hot acid applications including hydrochloric acid, sulfuric acid, acetic acid and nitric acid. Tantaline's acid resistant diaphragm valves offer a corrosion resistance beyond nickel alloys (Hastelloy), Titanium (Ti) and Zirconium (Zr). Valve Suppliers. Teaming up...

Hayward Flow Control
Manual Diaphragm Valves GENERAL DESCRIPTION. Overview. Hayward all-plastic diaphragm valves are engineered to provide superior handling of difficult media such as corrosive fluids, abrasives and slurries. They can also be used for high purity and sanitary applications. Manual or Automated. Available in manual or actuated (pneumatic or electric) models, the valves can be used for on/off and throttling service, feature a multi-turn design for precise control, and are self-draining on one side so that little to no dead...

GF Piping Systems
New Generation Diaphragm Valve The new Generation Diaphragm Valve of GF Piping System sets new standards regarding safety, efficiency and simplicity. Instead of the commonly used four metal screws it has a central union nut - this non-corrosive connection is characterized by homogeneous temperature behavior, an even surface pressure and high pressure rating up to 240PSI. The optimal flow geometry offers double the Cv values. With almost linear flow characteristics this guarantees stable processes. The weir of the zero-static...

GF Piping Systems
Pneumatic Diaphragm Valves DIASTAR The new pneumatic Diaphragm Valves of GF Piping Systems represent a revolution in terms of safety, efficiency and simplicity. Like the hand valves the new DIASTAR also has a central union nut. This connection is non-corrosive, temperature stable and high pressure rating up to 240PSI. Because of the doubled Cv values the energy expenditure can be reduced considerably. At the same time the flow characteristic is very linear and thus ideally suited for control applications. Features like rotatable... (read more)Browse Diaphragm Valves Datasheets for GF Piping Systems

Beyond the basics such as flow rate, temperature, voltage and media compatibility, there are a host of other critical issues necessary to determine the best pump for your system design. The fundamental design criteria for selecting an electrically operated diaphragm pump to handle air or gases has...

An example would be a full port/full open 1" ball valve with a typical Cv of 40 versus a full open 1" diaphragm valve with a typical Cv of 15. 7. What is Backpressure? - Backpressure is simply defined as the pressure...
