Product Details
Place of Origin: Guangdong, China (Mainland); Brand Name: Jewellok; Certification: CE; Model Number: JW-200; Minimum Order Quantity: 1-9 Pieces; Price: Negotiable

Short Description
Stainless steel high-pressure specialty gas changeover manifolds enable continuous supply of high-purity gases (O2, N2, Ar, He, H2, CO2) by connecting multiple cylinders and automatically switching to a full source when one is depleted. Designed for uninterrupted, contamination-sensitive industrial and laboratory gas supply.

Product Description (JW-200 Series)
The JW-200 Series is a stainless steel, high-pressure changeover manifold for cylinder banks with pressure relief on both sides. It provides automatic changeover for continuous supply and includes a purge function for diaphragm valves. Maximum inlet pressure up to 20.7 MPa (3000 psi). Assembled and tested in a clean workshop environment to support high-purity gas applications such as gas analysis and semiconductor processes.

Key Features

• Purge function for diaphragm valve
• Supplied with three Jewellok series pressure regulators (compatible with other regulators)
• Configurable continuous supply layouts: 1×1, 2×2, 3×3, 4×4
• Automatic changeover detection and switching to maintain uninterrupted flow
