PRESSURE REGULATORS. GUIDE to REGULATORS and SERVO VALVES

Transcription

1 Master Pneumatic regulators are made in a wide range of sizes to suit nearly all industrial requirements for pneumatic pressure regulation. Good pressure regulation is essential to the efficient use of pneumatic equipment. A compressor may supply air at 15 psig, but most of the equipment will operate best at lower pressures. A cylinder, for example, may develop sufficient force for its purpose with 5-psig air. Remember that compressed air is costly, so using higher air pressure than necessary is wasteful, and may also shorten the life of the cylinder. A general purpose pressure regulator is the answer for greater economy and efficiency. PRESSURE REGULATORS GUIDE to REGULATORS and SERVO VALVES Regulators are of two basic designs. Piston design provides highest air flow; diaphragm design provides high sensitivity and quick response. All regulators are self-relieving, but a non-relieving option is available. A pressure gauge is standard, and gauge ports are at the front and the rear of each unit. In addition there are precision regulators in all port sizes for applications demanding extra precision in the regulation of air pressure, plus regulators for remote, external piloting. MODULAR or INLINE MOUNTING SENTRY, GUARDSMAN, SERIES 35, SERIES 38, and Full-Size VANGUARD regulators are of modular design. Regulators are connected to filters or lubricators by special modular connectors which seal the faces between units. They may also be inline mounted with pipe nipples. MINIATURE and High-Capacity VANGUARD regulators are inline mounted only. SENTRY REGULATORS Port sizes 1/8 and 1/ or fittings for tubing up to 1 mm. Modular units have durable plastic, corrosion-resistant bodies. A non-relieving version can be used with water, oil, and many other liquids.

2 MINIATURE REGULATORS Port sizes 1/8, 1/. Aluminum-bodied units for inline mounting. Same performance characteristics as the SENTRY models. Brass or stainless steel bodies, and water pressure models are also available. PRECISION MINIATURE regulators are available to provide outstanding pressure control at relatively low cost. A large diaphragm area gives high sensitivity, and a small valve seat gives greater precision and little variation in outlet pressure from fluctuations in supply pressure. With an inlet pressure of 1 psig (7 ), repeatability is within 1/ psig. Regulated pressure range is psig (.1 ). Optional springs allow other pressure ranges. GUARDSMAN REGULATORS Port sizes 1/, 3/8, 1 /. Modular units in a balancedvalve, piston design with very quick response for fast-cycling valves and cylinders. Two sub-series: R models with durable plastic dome, and R75 models with high-strength metal dome for more severe environments. Regulation performance is essentially the same. SERIES 35, SERIES 38 and VANGUARD REGULATORS Port sizes 1/ to 3/. Modular units with diaphragm design for sensitivity and accurate pressure regulation. An adjustment-locking key to prevent tampering is standard. Full-Size VANGUARD SERIES 35, and SERIES 38 PRECISION regulators are also available. They are of diaphragm design, and were developed to give superior torque control with pneumatic tools. However, they are well suited to many other applications because of their ability to regulate very high air flows with great precision. They will hold regulated pressure within 3 psig (. ), and repeatability is within.5 psig (.3 ). For torque control and applications that cannot tolerate over-pressurization, regulated pressure can be limited to 85 psig (5.9 ). Air from a constant bleed, which is important to the precision of these units, is normally inaudible. HIGH- VANGUARD REGULATORS Port sizes 3/ to 1-1/. Inline mounting and piston design are featured in these high-air-flow models. An adjustment-locking key to prevent tampering is standard. PRECISION High-Capacity regulators are also available. They are of diaphragm design, and have essentially the same precise operating characteristics as the Full-Size VANGUARD precision regulators described above. Their larger port sizes, however, make them the choice for very high-air-flow applications. EXTERNALLY PILOTED REGULATORS Regulators operated with external pilots are as precise as the external pilot regulators used. A 1/ R55M pilot regulator (or R57M precision model) provides an accurately controlled air spring for excellent regulation. The pilot control regulator can be installed at a distance from the main regulator for convenience in making adjustments. Full-Size VANGUARD PRH1 modular external relief piloted regulators use a diaphragm design for high sensitivity. They provide air flows up to 1 scfm (9 l/s) in applications where low pressure drop and/or remote adjusting are desired. High-Flow PR18 VANGUARD external piloted regulators and High-Flow PRH18 VANGUARD external relief piloted regulators are of diaphragm design, and provide air fl ows up to scfm (8 l/s). High-Flow R VANGUARD Regulators provide air fl ows up to 1 scfm (7 l/s). For fast response, good sensitivity, and long service life they employ a piston traveling in a hardanodized, Tefl on-impregnated, metal cylinder. A high-fl ow, self-relieving valve is built into the main regulator. RELIEF VALVES Relief valves are set for a de sired maximum sys tem pres sure, and in sert ed in a tee down stream of reg u lat ed pres sure to prevent over-pres sur iza tion of the sys tem beyond the relief valve set ting. Relief valves are adjustable from 1 to 15 psig (.7 to 8. ). Optional springs are avail able for oth er pressure rang es. If pres sure exceeds the relief valve setting it will dump system air to at mo sphere or to a valve to provide a warning signal. Port sizes 1/8 and 1/. A pres sure gauge is stan dard equipment. ELECTRO-PNEUMATIC SERVO VALVES Electro-pneumatic servo valves employ the latest in closed loop control tech nol o gy. Flow rate is typically one scfm, but when used with a volume booster a fl ow rate in excess of 1, scfm can be achieved. Master Pneumatic, Inc. 133
