UNV Series

Problem solver - unrivalled flexibility of end connections 6000 psi rated

Description

The unique range of universal body needle valves offers the ultimate in instrument valve flexibility, any combination of end types i.e. 1/2” socket weld x 1/8” compression end or 1/2” NPT x 3/8” BSPP male. The combinations from 1/8” to 1/2” are limitless, why use reducers, male studs or adapters when you can now buy custom made valves. Less fittings used at the time of installation means more money is saved and the safer it will be. All joints are pre-tested at our factory. Available in straight or angle pattern body format the UNV is a compact problem solver - and its available in small quantities.

Features

Temperature rating -50°C to 230°C

Actuating threads are above the packings to prevent contamination by the process medium.

Available in straight or 90° angle pattern body style.

Repair / service kit available to extend field life further.

100 % Hydrostatic testing

Full material traceability.

The Alco Midget Valve

Description

The Alco Midget™ needle valve is an economical and compact solution for medium or low pressure applications. The Alco Midget™ has a soft tip for low pressure sealing on gas applications. Rated up to 3,000 psi the Midget is the baby of our needle valve range. It has significant applications in most industries where medium and high pressure gases are used. PTFE and Viton® packings are used -50°C up to +170°C (see temperature curve) options such as hand wheels or locking devices are also available.

OB series

Oblique Needle Valve 6,000 and 10,000 psi rated

Description

The in-line oblique needle valve, 6,000 psi and 10,000 psi versions. Far less pressure drop and flow restriction than a standard needle valve due to the near-straight bore through the valve. Operator friendly due to the angled head unit and handle. Particularly good for use with heavy or viscous fluids. Available in male x female and female x female versions. Options such as hand wheel and locking device available.

AV series

6,000 and 10,000 psi Angle Pattern Needle Valve

Description

The 90° angle pattern needle valve offers high pressure bubble tight sealing in a compact body allowing pipe work origination to change by 90° at the valve. The “AV” offers many different connections, male x male, male x female, threaded and even compression type tube ends. Pressure ratings 6,000 psi and 10,000 psi. Sizes from 1/4” to 1”. Several options such as locking device and hand wheel operator are available. The “AV” series is made in 316 stainless steel as standard and various super alloys. Features

Temperature rating -50°C to 230°C (570°C with GP option).

Ingress seal fitted as standard.

Full material traceability.

100% Hydrostatic testing.

Material of construction can be supplied to meet the requirements of NACE MR-01-75

FN Series

Compact, Forged Body Needle Valves

Description

The ‘FN’ series, forged body valve range utilising a one piece high strength forged 316 stainless steel body. The ‘FN’ series also offers non-rotating hardened tip for extended service life. Working pressures are 6,000 psi and 10,000 psi. Maximum working temperature up to 230°C and up to 570°C with GP option (at reduced pressure). The FN series is available in straight or 90° angle pattern body version with many other standard options available such as single nut style panel mounting facility, hand wheel and locking device.

XN Series

20,000 psi & 40,000 psi rated

Description

The “XN20” and “XN40” series needle valves are rated at 1,334 BAR (20,000 psi) and 2,667 BAR (40,000 psi) respectively cold working non shock. The tip assembly is specifically designed for heavy duty service with a fine metering tip to reduce impact on down stream equipment, instruments or test pieces. For use on very high pressure process lines and test equipment or for systems where standard pressure ratings are exceeded for extra safety. The “XN” comes with over-pressure or seal failure weep holes for extra safety. The “XN” is available in 316 stainless steel and certain other corrosion resistant super alloys. Certain options are available such as locking device and hand wheel etc.

NVSS Series

Temperatures in excess of 700° Celsius

Description

The NVSS severe service needle valve range has been specifically designed to cope with very high temperature / high pressure applications. Designed to meet the requirements of ASME B16.34 and fire tested to BS6755 part 2.
