DESCRIPTION

Positive Seal Tied-Seats two stage regulators are designed for use with critical and ultra-high purity corrosive gases, such as those used in semiconductor manufacturing. These regulators feature convoluted stainless steel diaphragms and tied seats (tied diaphragms) in both stages providing for greater sensitivity and sealing integrity. The two-stage design provides constant outlet pressure regardless of changes in cylinder (inlet) pressure.

FEATURES

• Tied Seats in both stages ensure positive shutoff if particulate matter should lodge in the seat, a common problem with corrosive gases.
• Metal-to-Metal Diaphragm to Body Seal (without back-up o-ring) assures maximum diffusion resistance.
• Type 316 Stainless Steel Bar Stock Construction provides corrosion resistance.
• 1⁄16" NPT female Bonnet Vent Ports and Stem Packing allow for complete capturing of bonnets when connected to a vent line or disposal system.
• Two-Stage Regulator Design ensures constant delivery pressure over varying inlet pressures.
• Regulator Design permits vacuum purging of regulator.

• Diaphragm Seal Outlet Valve maintains gas purity

• Filters trap foreign matter, extend regulator life and reduce maintenance.
