Fixed Ball Valve HN106

Product Overview

The HN106 Fixed Ball Valve is designed for on-off shut-off service in ANSI pipeline systems. The fixed ball structure supports the ball with trunnion-style bearing components, helping reduce operating torque and improve stability in larger sizes or higher pressure classes.

This valve series is suitable for oil, gas, water, steam and compatible industrial media where reliable quarter-turn isolation is required. Typical applications include petrochemical, refinery, power plant, pipeline and general industrial services.

HN106 can be supplied with raised face, butt-welded or ring type joint end configurations depending on pressure class and project requirements. The catalog reference covers Class 150, 300, 600, 900, 1500 and 2500 configurations, with fire-safe, anti-static, injection and gear/operator options available according to project specification.

• Handle, worm gear, electric, pneumatic or hydraulic operation may be selected according to size and torque requirements.

Sectional Structure and Materials

The numbered sectional drawing corresponds to the position numbers in the materials table. Final material selection should be confirmed according to pressure class, temperature, medium compatibility and project specification.

Note: A105 + ENP seat options, winding graphite gaskets and alternative material combinations may be selected according to operating medium, pressure class, temperature and service conditions.

Technical Specifications

Dimensions and Performance Data

The drawings show dimensional symbols such as L, L1, H, d and W used in the tables below. Values are catalog reference data for preliminary selection and should be confirmed against approved drawings before order.

Design and Construction Options

Available construction options may include handle, worm gear, electric, pneumatic or hydraulic operation; full bore or reducing bore selection; raised face, ring type joint or butt-welded end connections; PTFE or graphite packing options; anti-static design; fire-safe design; injection/sealant fittings; and fixed ball bearing support according to service conditions.

For fire-safe, anti-static or injection service requirements, the final configuration should be confirmed according to the required project standard, medium, temperature, pressure class and inspection requirements.

Frequently Asked Questions

What is HN106 mainly used for?

HN106 is mainly used for quarter-turn shut-off service in ANSI pipeline systems, including oil, gas, petrochemical, water, steam and compatible industrial media.

What is the difference between HN106 and HN105?

HN106 is a fixed ball valve designed for larger sizes or higher pressure classes, while HN105 is a floating ball valve for compact quarter-turn shut-off service. Final selection should be based on size, pressure class, operating torque and project specification.

Which pressure classes are available?

The catalog reference covers Class 150, Class 300, Class 600, Class 900, Class 1500 and Class 2500. The available size range depends on the selected pressure class and end connection.

Can HN106 be supplied with RF, BW or RTJ ends?

Yes. Raised face flange, butt-welded and ring type joint end configurations may be selected according to pressure class, piping design and project specification.

Is HN106 fire-safe and anti-static?

Fire-safe and anti-static construction may be selected according to API 607, BS 6755 and API 608 project requirements. Final configuration should be confirmed before quotation.
