We introduce new generation multi stage double meter gas regulators to give you continuous and trouble free service. President multi stage double meter gas regulators are precision engineered and designed in accordance with prescribed industry standards and parameters to deliver superior performance and extended service life. The regulator body and bonnet are specially forged from extruded brass rod thus eliminating casting porosity. The forged body can withstand one and half times the full cylinder pressure.

The diaphragms of the regulator are specially made from nylon reinforced neoprene rubber. All regulators are specially manufactured and tested as per Indian Standard IS:6901. Our regulators can be used with various gases, such as - Oxygen, Hydrogen, Nitrogen, Argon, Acetylene and Carbon Dioxide. High in functionality, our regulators can be used for diverse applications, such as - brazing, cutting, heating, welding, beverage plants, calorimetry, chromatography, purging, research lab and more.

These multi-stage regulators are intended for pressure control of ultra high purity gases for applications requiring constant pressure control and delivery regardless of supply pressure variations. They feature a 316L stainless steel diaphragm with a metal-to metal diaphragm seal to give no possibility of gas contamination. Internal seals and seat are PTFE resin. Maximum inlet pressure is 3000 PSIG and gauges are 2" diameter. Helium leak integrity is 1 x 10-9 scc/sec. Outlet ports are 1/4" FPT.

Manifolds, Valves and Regulators

The following information applies to the use of manifolds, valves and/or regulators:

   1. Where compressed gas containers are connected to a manifold, the manifold and its         related equipment, such as regulators, shall be of proper design for the product(s) they         are to contain at the appropriate temperatures, pressures and flows.
   2. Use only approved valves, regulators, manifolds, piping and other associated equipment in        any system that requires compressed gas. Care must be taken to ensure that pressure        gauges on regulators are correct for the pressure of the gas cylinder used. With the        exception of lecture bottles, threads, configurations and valve outlets are different for        each class of gases to prevent mixing of incompatible gases.
   3. CGA Pamphlet V-1: Standard for Compressed Gas Cylinder Valves, lists the appropriate        valve for each gas. Manufacturers and distributors should also be able to identify the        valves and associated equipment required for each gas.
   4. Lecture bottles use universal threads and valves, some of which are interchangeable.        Label all associated equipment with the gas name to prevent unintentional mixing of        incompatible materials.
   5. Valves and regulators should undergo periodic maintenance and repair. A visual inspection        should be performed before each usage to detect any damage, cracks, corrosion or other       defects. Long term maintenance or replacement periods vary with the types of gases        used, the length of use, and conditions of usage. Consult the cylinder, regulator or gas        supplier for recommended valve and regulator maintenance schedules.
   6. Valves and regulator maintenance histories should be known before usage. Valves that        pass visual inspection are still subject to failure, therefore it is critical that toxic or         poisonous gases (see Appendix C) are used in ventilated enclosures and have local        exhaust ventilation in place for downstream pressure relief valves, etc.
   7. Valves and regulators should only be repaired by qualified individuals. Valve and regulator        manufacturers, gas supply companies, or valve and regulator specialty shops should be        consulted for any repair needs.
