Alco Valves manufacturers some of the worlds largest line of Industrial Valves available. 

Ball Valves

The multiport gauge (ball valve) is designed to provide an economical method for mounting gauges with the facility to test and calibrate gauges and pressure switches. As an option the '3' series is supplied with screw-in vent and blanking plugs to facilitate the vent / testing. The ‘3’ series, being a ball valve construction / clear bore, offers roddability due to it’s straight through flow passage.

The 3-way L-Port diverter valves are an economical and safe method of diverting high pressure lines, saving the use of several high pressure 2-way valves. Ensuring an altogether safe, compact and easy to install solution to high pressure diversion

The 4-way multi diverter valves are an economical and safe method of diverting high pressure lines, this replaces several high pressure 2-way valves. Ideal for sampling or vent / dumping applications. Ensuring an altogether safe, compact and easy to install solution to high pressure diversion, using the inlet pressure to actuate the floating ball ensuring a tight seal on the seat.

The Alco 3T series “T” ported high pressure diverting ball valve range offers a compact and safe way to divert, control, vent, or sample high pressure liquid or gas mediums.

The USB offers low torque smooth positive action with floating seat design. 4-piece flexibility, with the added advantage of single nut panel mounting facility. Dynamic seats and Trunnion Mounted Ball design, a compact way to divert high pressure lines safely.

The ‘PB’ Series high pressure 3 piece ball valve, like it’s lower pressure range brother the ‘B’ Series, it offers flexibility where by the end connection sizes and types can be mixed i.e. PB4NS-12N offers 1/2” to 1/4” reduction in size across the valve.

The rugged SSB range of Fire Safe Ball Valve is manufactured in 316 stainless steel (and certain super alloys). Available in sizes from 1/4” to 1”.

The 'SSB'series has soft polymer primary seats which allows use with gas or liquid mediums up to 3,000psi (207bar). The secondary metal-to-metal seating is for fire conditions.

The SSB range offers Drop-centre accessibility for welding / positioning / pipe access or maintenance purposes. Fire safe tested to BS 6755 Part 2 and API 6FA / API 607.

The Panel Mount range or the ‘PSB’ series is a variation of the standard ‘B’ series and as such retains it’s flexibility of end connections with the added advantage of the panel mounting facility onto a flat face. Using this flat face, the valve is easy to mount to a control panel, cabinet / enclosure or actuator

The A Series is proven to be better than cast type products. The high quality ‘A’ series low to medium pressure ball valve range is an economically designed valve with the internals being loaded through the end threads. Manufactured in high specification, High integrity 316 S11 dual certified 316/316L Stainless Steel to N.A.C.E. as standard

The UB series high pressure valve has a working pressure of 10,000 psi with a body test at (15,000 psi). The UB Series is a tried and tested rugged design for high pressure applications. It comes with panel mounting holes and stainless steel handle as standard. Service / repair kits are available to prolong service / field life.

The bolt together style or ‘S’ Series valve offers flexibility and interchangeability. It is manufactured with the choice of threaded, socket or butt weld ends for installing the valve into the pipeline.

Alco Offers a full range of electrically actuated ball valves that can be supplied in sizes 1/4” to 2 1/2” and pressure ranges from 1,000 psi to 10,000 psi. A full complement of accessories can also be supplied, i.e. limit switches, solenoids, etc.

The precision made ‘N’ series, single isolation hand valve utilizing metal to metal seat and body to bonnet connection for superior, bubble tight sealing capabilities at both extreme pressures and temperatures.

The precision made ‘UN’ series, single isolation hand valve utilizing metal to metal seat and body to bonnet connection for superior, bubble tight sealing capabilities at both extreme pressures and temperatures. Although this unit appears to be the same as it's lower pressure brother, the 6,000psi rated 'N' Series, there are significant differences in the packing materials used for this higher pressure unit.

Tube / Compression Ended Needle Valves. The standard ‘N’ series with compression type tube fitting ends.Tube fittings available include Twin and single ferrule type.

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 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 in-line oblique needle valve, "OB" Series 6,000psi and "UOB" Series 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.


 

MANIFOLD AND GAUGE VALVES

The "GV" series provides an economical method of mounting pressure gauges, manometers, pressure transducers or transmitters and includes vent and blanked port facilities or additional drains in a circuit or system.
