Advanced Specialty Gas Equipment

MANIFOLDS
SR Series
Modular, Single Row, High Purity Manifolds

Manifolds are used to connect two or more cylinders together for greater on-line storage capacity or higher flow rates. These single-row, wall-mounted manifolds are available in either Brass or Type 316 Stainless Steel construction and are provided with diaphragm seal station valves, 3-ft. pigtails (stainless steel CGA connections with flexible pigtail option) and wall mounting brackets as standard components.

The SR Series is designed for "right side" cylinder orientation, where the gas flows from right to left through the manifold header."Left side" set-up is available upon request. The SR Series manifolds are manufactured to meet the requirements of the ASME B31.3 Process Piping Code. The brass manifolds are constructed of 7/8 inch OD 0.200 wall CDA-330 brass seamless tubing, npt threaded and silver braze assembled. The stainless steel manifolds are fabricated with 5/8 inch OD, 0.065 wall, Type 316L stainless steel tubing and socket TIG weld assembled. ASGE's enhanced manifold header design exceeds industry standards by providing a 4 to 1 - burst to maximum operating pressure safety factor.

Warning: Manifolds are designed to distribute a single gas from two or more cylinders. Never mix gases in a manifold. Injury to personnel or damage to equipment may result.

Standard Features
  • Modular Construction allows field installation of additional stations without welding or soldering.
  • Diffusion Resistant, Diaphragm Seal Station Valves ensure that gas purity is maintained and allow cylinder removal from a manifold without interrupting gas flow.
Optional Features
  • Master Shut-off Valve allows manifold to be isolated from downstream system.
  • Double-Braided (All Metal) 3' Stainless Steel Flexible Hose Pigtails with Stainless Steel CGA connections extend service life and provide ease of connecting cylinders.
  • Check Valves prevent discharge of gas from manifold and pigtails when changing cylinders (required for flammable gases).
  • Pressure Switches monitor line pressure and can activate an external alarm when a certain predetermined pressure is reached.

Ordering Information

To order a single row manifold, complete the part number using the "Part Number Key". For example, to order a 5 cylinder, stainless steel, single row manifold, with rigid pigtails, check valves, and with CGA 580 connections, the part number would be SRS-4-5-580. Order by complete part number.

Manifolds for Acetylene Service require flashback arrestors (SG6545). All manifolds ordered with CGA 510 will be shipped with flashback arrestors installed on each pigtail, unless the order specifies with which gas it will be used.

Warning: Advanced does not recommend the use of stainless steel manifolds for Oxygen service and will not provide such manifolds with CGA540 connections.
