The Industry Standard for Pressure Regulators

Product catalog summary
Introduction
This document is a comprehensive guide for selecting pressure regulators for applications such as air, steam, tank blanketing/vapor recovery, liquids, process, and fuel gas. It includes conversion tables for temperature, pressure, and volumetric flow, essential for understanding regulator specifications.
Temperature and Pressure Conversion
Formulas for converting temperatures between Fahrenheit, Celsius, and Kelvin are provided, along with a table for converting pressure units like bar, kPa, mm Hg, mm H2O, kg/cm2, psi, and in Hg.
Volumetric Flow Conversion
Tables for converting volumetric gas and liquid flow rates between units such as Nm3/hr, SCFH, SCFM, in3/min, and Nliters/min for gases, and l/sec, l/min, m3/h, ft3/min, ft3/hr, US gal/min, UK gal/min, and barrels/min for liquids are included.
Regulator Types and Applications
Regulators are categorized by application: air, steam, tank blanketing/vapor recovery, liquids, process gas, and fuel gas. Each category lists specific series and types, such as MR95, 67C, and 92B, detailing operational methods, body sizes, maximum inlet pressures, and flow capacities.
Pressure Reducing Regulators
These regulators maintain desired outlet pressure while meeting downstream demand. They are divided into direct-operated and pilot-operated types, with direct-operated suitable for low-pressure applications and pilot-operated preferred for high flow rates and precise control.
Relief Valves and Backpressure Regulators
Relief valves relieve fluid during overpressure, while backpressure regulators maintain constant upstream pressure. The document describes direct-operated and pilot-operated relief valves and provides selection criteria for backpressure regulators.
Selection Tables
Detailed selection tables list outlet pressure ranges, operation methods, body sizes, maximum inlet pressures, and flow capacities for various regulator types and series.
Tank Blanketing Regulators
  • Type T205B: Direct-operated with balanced plug design for low-pressure settings, featuring a large diaphragm for accurate control.
  • ACE95 Series: Pilot-operated, ideal for low-pressure blanketing with high sensitivity and accuracy, suitable for tank blanketing and vapor recovery.
  • Type Y692: Direct-operated for very low-pressure blanketing with quick response and precise control.
  • Type 1190: Pilot-operated for accurate pressure control and protection against atmospheric contamination.
Vapor Recovery Regulators
  • T208 Series: Direct-operated for small vapor recovery systems, functioning as a backpressure or relief valve.
  • Type 1290: Pilot-operated, high-capacity valve for monitoring tank vapor pressure, unaffected by recovery system pressure changes.
Pressure Reducing Regulators
  • Type MR105: Direct-operated, high-capacity regulator for various applications, meeting API 614 standards.
  • Type 92W: Pilot-operated for high cycle liquid service with durable stainless steel trim.
  • Type 1098-EGR: Pilot-operated for accurate and fast response in low-pressure drop systems.
Relief/Backpressure Regulators
  • Type 63EG-98HM: Compact, fast response valve for gas or liquid service, ideal for pump recirculation.
  • Type MR108: Direct-operated, high-capacity regulator for multi-purpose applications, providing reliable backpressure control.
Materials and Construction
Regulators are made from materials like cast iron, steel, stainless steel, Hastelloy® C, and Monel®, ensuring compatibility with various fluids and gases. They are designed to withstand different temperature ranges and pressures, with models offering high sensitivity, tight shutoff, and in-line maintenance capabilities.
Specifications
  • T205 Series: Compact regulator for low-pressure systems, available in NPS 3/4 and 1 sizes, with a control pressure range of 1 in. w.c. to 7 psig.
  • T205VB Series: Vacuum breaker for accurate vacuum protection, available in NPS 3/4 and 1 sizes, with a control pressure range of 0 to 5 psig.
  • MR98 Series: Used for backpressure and relief applications, available in various sizes, with a relief pressure range of 2 to 375 psig.
  • Type 310A: High-pressure regulator for high-capacity applications, available in sizes up to NPS 4 x 6, with an outlet pressure range of 10 to 700 psig.
  • Type EZR: Designed for natural gas systems, available in multiple sizes, with an outlet pressure range of 6 in. w.c. to 1000 psig.
Procedures and Recommendations
  • Ensure overpressure protection is installed to safeguard regulators and downstream equipment.
  • Check inlet pressure at the regulator body inlet connection to avoid significant pressure losses.
  • Use the smallest orifice that can handle the flow to avoid oversizing regulators.
  • Install control lines of equal or greater size than the control tap on the regulator to prevent delayed response.
  • Ensure vents are pointed down to prevent accumulation of condensation.
Installation and Maintenance
  • Diaphragms may leak small amounts of gas; ensure casing vents remain open.
  • For relief valves, set the relief valve setpoint above the regulator setpoint to avoid seepage.
  • Install control line connections downstream of turbulence areas to ensure stability.
