• True "Floating" Ball Valve design is seat wear compensating
• Micro finished ball for positive shut-off.

Parker Miniature Instrumentation Ball Valves, with their rugged compact design, offer positive shut off of fluids in process, power and instrumentation applications. These valves are available in 2-way and 3-way configurations, brass and stainless steel construction, with a wide variety of port connections. Also, all ports are suitable as inlets to full operating pressure of the valve.

These are designed for positive leak tight shut-off of fluids in process, power and instrumentation application. A 90° rotation of the stem provides quick on-off service for both manual and remote actuated valves. Its roddable, straight though flow path provides maximum flow with minimum pressure drop across the seat.

Compact quarter-turn valves are manufactured from stainless steel or brass bar stock and offered in a variety of port connections. The straight-thru design provides minimum pressure drop.

Sample Cylinders

Parker sample cylinders permit samples to be drawn from remote processes and provide safe containment during transfer to the laboratory for analysis.

Needle valves are available in forged or bar stock bodies with port sizes up to one inch. Applications include multi-turn shut-off and coarse regulation in moderate to severe service pressures and temperatures.

The RG Group offers a broad line of precision metering valves for use in analytical instrumentation, research laboratories and other applications. The valves are designed to provide accurate and stable control of low gas and liquid flow rates. A variety of connection sizes, body patterns, and materials of construction provide considerable application versatility.

Adjustable
Relief Valves

RG offers proportional relief valves with externally adjustable pressure settings. Optional manual override permits relief of pressure regardless of the set point.

Provide unidirectional control of liquids and gases and are offered in numerous sizes and variety of inch/metric port connections, including CPI™ and A-LOK™ compression and male and female NPT.

Ultra High Purity Valves

DIAPHRAGM & BELLOWS VALVES - Parker UHP Diaphragm and Bellows valves provide a contaminant free, positive shut-off for high purity gas/fluid systems. These 1/4" - 1/2" size analytical and process control valves offer superior leak integrity for manually and pneumatically actuated applications with pressure ranges from vacuum to 3500 psig.

CvMax FULL FLOW BELLOWS VALVES -

Bulk Gas Systems Valves

A broad line of valves and integrated components for bulk gas and facility distribution applications. Valves ranging in size from 1/2" - 6" include springless and non-rising stem designs with a variety of end connections, and purge port options.

features:

• Straight through bore provides maximum flow with minimal turbulence
• 316L Stainless Steel VIM/VAR or AOD/VAR body material minimizes sulfur and reduces impurities that cause surface anomalies
• Stainless Steel packless bellows design for critical application
• Replaceable nickel gasket for atmospheric seal
• UHP electropolished finishes available at 5, 7, 10 and GP finishes at 20 Ra
• Color-coded handles available.

precise control for air applications. Stainless steel, brass, and aluminum.

A unique set pressure regulators that uses a pressure-sensing assembly to control delivery pressure. Unlike conventional regulators that use a heavy spring against a stiff diaphragm, this assembly provides an exact pressure reference rather than a spring reference. The assembly is charged with argon to precisely set the desired process gas delivery pressure.

Manufactured in a Class 10 clean room environment. Single port and flow through pressure transducers are specifically designed for the semiconductor industry.

FOR HIGH PURITY APPLICATIONS... Designed and developed for high purity process applications. These applications include the monitoring and control of gas delivery systems, vacuum pumps/chambers and process media recovery systems. The switches are; unaffected by exposure to high vacuum, resistant to shock & vibration, small size for easy installation and have electron beam welds for "leak-tight" integrity.

FOR PROCESS APPLICATIONS…Designed for process applications and are factory set to your specification and can be easily modified. Their construction makes them suitable for a wide range of media including air, inert gases, hydraulic fluid, oils, and other non-corrosive media.

Fixed and adjustable pressure switches designed for use in corrosive high purity gas and wet process applications where 316L stainless steel is not acceptable. The design advantages include a crush seal for leak tight integrity plus external plastic parts that remain unaffected by chemical spills or splashes.

Small and accurate flow switches are compatible with a wide range of media and feature a simple operating principle for years of trouble-free service. Common use include pump & heater control, low and high flow warnings, and pump safety shutoff.
