PORTER Precision Pressure Regulators

Pressure Regulator Pressure Regulator Link

Engineered to excel in critical low flow/low pressure applications

Porter precision regulators are designed specifically for critical service in analytical instrumentation. All models are direct-acting, non-relieving, and are supplied with a sintered stainless steel cartridge filter on the inlet. We offer several distinct models with a variety of process connections, spring ranges and diaphragm materials to satisfy the most demanding instrument applications.

NOTE FOR OEM MANUFACTURERS
We can design custom variations of our standard product to fit customer defined requirements.

PORTER PRECISION PRESSURE REGULATORS...Finely crafted - sharply accurate and highly adaptable to your application specifications in industrial, analytical and medical instrumentation

  • Distinctive Valve/Seat Design
    A Precision Glass Ball & Quad Ring on Models 8310 / 8311 provides exacting regulation in a variety of low flow instrument specific applications. The Model 8286's Pneumatically Balanced Poppet minimizes supply pressure effect in higher flow applications.

  • Choice of Diaphragm Materials
    Stainless Steel Diaphragms provide extremely low permeability. Coated Fabric Diaphragms, available in Buna N or Viton, offer unmatched sensitivity.

  • Fine Pitch Adjusting Stem
    56 Thread per inch pitch on all regulator-adjusting stems gives 15-turn resolution for precise control over incremental pressure adjustments

  • Barstock Construction and Analytical Service Cleaning
    PORTER regulators are machined from bar stock in your choice of aluminum or stainless steel. All parts are cleaned to procedures developed specifically for analytical service. This minimizes contaminant generation in low-level analyzer applications.

  • Extensive Choice of Range Springs
    2.5, 5, 10, 30, 60, 100 PSI Maximum ranges in Music Wire or Ni-Span are available in most models. This ensures maximum set-ability at specific pressure and temperature requirements.

  • Integral 100 Micron Sintered Stainless Steel Cartridge Filter
    Models 8310, 8311 and 8286 are supplied with a replaceable sintered stainless steel cartridge filter on the inlet to help reduce regulator failure from media contamination
