Functional Performance
GENTEC products are engineered for high accuracy and durability, offering flow capacities from Cv=0.054 to Cv=1.8 and maximum leak rates as low as 0.5 x 10-9 atm cc/sec He. They feature proof and burst pressures significantly exceeding maximum rated pressures.
Materials and Construction
Products are made from high-quality materials like 316L stainless steel, PCTFE, and Vespel®, with advanced CNC machining and electropolishing for precision and durability.
Operating Conditions
Designed for diverse conditions, products support maximum inlet pressures up to 3000 psi and temperatures from -40°F to 165°F.
Ordering Information
GENTEC offers detailed ordering options for product customization, including body ports, seat materials, pressure ratings, and connection types.
Specifications
Diaphragm valve series specifications include flow capacities (e.g., Cv=0.3 for DV54 and DV86), maximum leak rates, proof pressure (150% of maximum working pressure), and burst pressure (400% of maximum working pressure). Surface finish options and operating conditions are also detailed.
Pneumatic Actuator
Operating pressure ranges from 70 - 125 psi with 1/8”NPT (Female) inlet connections. Valves can be normally closed or open.
Materials
Components are constructed from 316L stainless steel, PCTFE or Vespel® seats, and Elgiloy® diaphragms.
Internal Volume
Varies by model, with 1.6 cc for DV54 and DV86, and 0.8 cc for DV82 and DV84.
Features
Valves are suitable for high purity applications, featuring metal-to-metal diaphragm seals, high-cycle life, and 100% helium leak testing, with manual or pneumatic actuation options.
Union Tee and 90° Union Elbow Specifications
Available in various sizes with specific pressure ratings, such as the 1/2 SL-MUT-8 Union Tee with a pressure rating of 3700 psi.
Vacuum Generators
Made from Stainless Steel 316L, these generators are helium leak tested and used in gas delivery systems for purging piping systems.
Conversion Factors
Includes conversion factors for flow and pressure units like psig, mbar, bar, and atm.
Material Compatibility
A table indicates material compatibility with gases, using symbols to denote recommendations.
Cylinder Connections Allocation
