260R Gas Regulator

Introduction

•The Model 260 Regulator is a lever operated, spring loaded regulator
•Use with confidence on natural and manufactured gases of non-aggressive nature, including nitrogen, carbon dioxide,
propane, butane, etc.
•Versions available for special applications like indoor applications with no requirement for vent-line
•Fixed factor billing model available (PFM) for applications that require accuracy to +/- 1% absolute pressure
•CSA 6.18 Service Regulator and CSA 6.22 Line Pressure Regulator Approved

Unique Feature

•Upon full regulator failure, outlet pressure is limited to under 1 psi (70 mbar) with 60 psi (4 bar) inlet pressure and full
bore relief discharge. Tested and approved to CSA 6.18 specifications

Characteristics

•Wide inlet pressure range 1-125 psi (0.07-8.6 bar) depending on orifice diameter
•Maximum inlet pressure 150 psi (10.3 bar)
•Maximum allowable operating pressure 125 psi (8.6 bar) depending on orifice diameter
•Lever-operated to accommodate changes in inlet pressure, spring-loaded for increased speed of response
•Various interchangeable orifices for ease of maintenance, customizability and increased turndown ratio to accommodate a
wide range of flow and pressure requirements
•Outlet pressure range from 4“ wc – 5.5 psi (10.0-385 mbar) over 6 spring ranges
•3 different inlet/outlet thread types (NPT, BSPT, BSPP) in ½, ¾, 1“ screwed both in-line (180o) or angle (90o) body
casting
•Various internal relief valve assemblies available (full, limited and none)
•1“ threaded vent connection
•Ease of maintenance due to interchangeable diaphragm casing cartridge
•Various integral safety slam-shut (SSV) models available for pressure/flow shut off protection.
•Custom designed and pre-fabricated regulator meter set assemblies available
