Product catalog summary
Overview
This technical catalog from Parker Hannifin Corporation provides comprehensive details on needle and toggle valves, specifically designed for instrumentation applications. It includes specifications, features, and ordering information for various series, such as the V Series Needle Valves, U Series Union Bonnet Valves, and VQ Series Toggle Valves.
V Series Needle Valves
These valves are engineered for leak-tight shut-off and fluid regulation, suitable for process, power, and instrumentation applications. They support a wide range of temperatures (-65°F to 450°F) and pressures up to 5000 psig. Key features include three stem types, differential hardness for enhanced cycle life, and options for PTFE packing or elastomeric O-ring stem seals. Materials used include 316 Stainless Steel, Brass, and Monel® Alloy 400.
Specifications
Pressure ratings vary by material, with 316 Stainless Steel valves rated up to 5000 psig, and Brass and Monel® Alloy 400 up to 3000 psig. Temperature ratings depend on the packing material, with PTFE allowing for a range of -65°F to 450°F.
Ordering Information
The catalog provides a systematic approach to ordering, with part numbers indicating characteristics such as connection size, valve series, stem type, and body material. Options for O-ring packing, body materials, and oxygen cleaning are available.
Warnings and User Responsibility
Users are cautioned about the importance of proper product selection and use to prevent hazards. They are responsible for ensuring all performance, endurance, maintenance, safety, and warning requirements are met.
U Series Union Bonnet Valves
Designed for high-pressure and high-temperature applications, these valves withstand up to 6,000 psig and 1,200°F. They feature a non-rotating lower stem to extend packing life and isolate thread lubricant from the flow.
Toggle Valves
Parker VQ Series Toggle Valves offer manual or pneumatic on-off control for moderate pressure and temperature applications, available in various configurations.
General Notes
All valves are 100% factory tested, with optional oxygen cleaning available. Dimensions are provided in both inches and millimeters.

U Series Needle Valves Introduction Parker U Series Union Bonnet Valves have been engineered for use at pressures up to 6,000 (414 bar) and temperatures as high as 1,200°F (649°C). A non-rotating lower stem helps to extend packing life by removing rotation from the packing area. Stem packing below the threads isolates the thread lubricant from the flow, ensuring adequate lubrication regardless of the media. Union bonnet design ensures high integrity seal under severe service applications Packing below the power threads protects thread lubricants from media and isolates the lubricants from the...
