Item Details

  • These two-stage regulators are specifically designed for low-flow, non-corrosive gas applications where precise delivery pressure is critical. They feature a brass piston sensor in the first stage, a stainless steel diaphragm in the second stage and a preset safety relief valve. A sintered brass filter protects internal parts. These two-stage regulators are also ideal for medical diagnostic applications, such as blood gas analysis, where precise pressure control and low flow rates are required. They are available with a CGA-cylinder valve connection for use on large cylinders.

Features

  • Convoluted Stainless Steel Diaphragms: Provides superior leak integrity without contamination from a non-metallic liner or seal.
  • Low Internal Volume: Allows rapid purging and stabilization of gas flow.
  • Low-Flow Design: Provides precise pressure and flow control.
  • Small Size: Enables fast, easy fit up.
