1 Worcester Controls 3-piece reduced bore ball valves Designed for a wide range of general services BS EN ISO 91 as FM 77

2 Almost years ago, Worcester Controls original 3-piece valve was responsible for the development of the UK ball valve market.the Series 44 rapidly established itself as the industry standard for quality, reliability and long service. As you would expect, Worcester has developed and improved the Series 44 over the years to maintain its position as the 8-mm valve design which others strive to equal (see Page 11). Now, Worcester s new, larger valve, the -1mm Series 49, complements the Series 44 to offer you the most versatile, reliable and widely specified range of 3-piece ball valves available. Actuator mounting Conforms to ISO 211 for ease of actuation (8-2mm valves use Worcester two hole pattern see page 4) Locking clip Maintains position of gland nut during actuation for long leak-free performance Gland nut Does not need to be removed for actuator mounting thereby maintaining valve integrity Wrench Ergonomically designed for ease of operation Anti-static stem design Ensures electrical continuity between ball and body Anti-blowout stem Inserted from inside of valve body for greater safety Seat design Cavity pressure relieving (CPR) seats ensure that pressure generated through media expansion when the valve is closed is safely relieved upstream Seats Wide range of seat materials to suit customer applications (see centre pages) Body connectors Available in screwed, butt weld, socket weld or solder ends to meet all major international standards or alternatively to meet specific customer needs Ball 31 stainless steel as standard with pressure equalising hole to balance cavity pressure with line pressure when valve is open Materials of construction Body and end connectors are manufactured from forged material (valve bodies, sizes and above, are from cast material). These larger sizes are also suitable for low temperature applications (to -4 C) as standard Body seals PTFE as standard for media compatibility but can be interchanged for alternative applications Bolting Bolting enclosed (44 series) to minimise corrosion and maintain alignment of body and end connectors.stainless steel valves are supplied with stainless steel bolting

4 Worcester Worcester Worcester Worcester Worcester Worcester Worcester Worcester Worcester Worcester Worcester Worcester Worcester Worcester Pressure/Temperature Ratings IMPORTANT see note on p.1 VIRGIN PTFE (T) Virgin PTFE is the most common sealing material and is suitable for almost all media as it has excellent chemical resistance. RE-INFORCED PTFE (R) Glass re-inforced PTFE seats are stronger than virgin and have higher pressure/temperature ratings.chemical resistance as per virgin PTFE. UHMWPE (U) Ultra High Molecular Weight Polyethylene offers good performance characteristics in applications where PTFE is not suitable (for example on tobacco duty). ACETAL (Y) Machined from acetal homopolymer, these seats are capable of handling extremely high pressures.please note this material should not be used on oxygen service [13] 1 1-mm 1 1-mm [7] NON SHOCK LIQUIDS (1-2mm) mm-mm 8 7 8mm-mm MAXIMUM WORKING 8 7 8mm-mm MAXIMUM WORKING 1 1 [138] NON SHOCK LIQUIDS (32-mm) [12] 1 GAS (1-2mm) 1 [83] 8 GAS (32-mm) [23] -3 [23] -3-3 [8] VXI (H) VXI is a glass re-inforced PTFE material offering a greater pressure/temperature capability than the R seat. FLUOROFILL (P) Carbon, glass and graphite filled PTFE material, an excellent seat material for steam and thermal services as well as having good abrasion resistance. Due to its high cycling capabilities, it is the recommended soft seat for modulating control applications. PEEK (X) PEEK is Poly Ether Ether Ketone, a material which demonstrates outstanding pressure capabilities at elevated temperatures.peek has excellent chemical and abrasion resistance. METAL ALPHA (A) A 31L sintered metal seat impregnated with PTFE, this material combines the strength and abrasion resistance of metal with the lubrication properties of PTFE.A graphite-impregnated metal seat is also available [13] 1 1-mm 11 [13] 1 1-mm 2 NON SHOCK LIQUIDS [7] (1-2mm) mm-mm mm-mm MAXIMUM WORKING 1 1 [138] [12] 1 1 [83] 8 NON SHOCK LIQUIDS (32-mm) GAS (1-2mm) GAS (32-mm) MAXIMUM WORKING mm-mm [2] [2] -3 [2] -3 [28] -3

When wrench not fitted flats on stem, when parallel to pipeline axis, denote ball open position. 3. All 8.mm weld end valves are assembled with Buna O ring body connector seals with the correct body seals supplied loose. This provides for the valves to be tested by Worcester Controls, disassembled by the customer to weld in line, and reassembled.instructions will be supplied for fitting fire seals. 4. Limiting stem input torque figures are based on random practical laboratory tests.. For temperatures below -3 C, consult Worcester Controls.. Installation, Operating and Maintenance instructions are available on request. Standards of Compliance Threaded Connections Socket Weld Connections Butt Weld Connections IMPORTANT NOTE Body connector screwed female to the following thread specifications: NPT ANSI B1..1 (NPT) BSPT ISO R/7.BS 21 (Rc) BSPP ISO R/7.BS 2779.BS 21. Body connectors bored suitable for accepting plain end pipe to the following specifications: BS 1 API L BS 3 Body connectors prepared in accordance with relevant material specification & ASME code section IX.For butt welding pipe to the following specifications: API L BS 1 schedules 8//1/ Pressure Test Specification BS 7 Part 1 and EN 17 Quality Assurance BS EN ISO 91 Due to continuous development of our product range, we reserve the right to alter the dimensions and information contained in this leaflet as required. The information given in the pressure/temperature graphs indicates the maximum performance capabilities of the seat materials.the full potential of virgin and re-inforced PTFE can be realised in the standard Worcester valve build.for more demanding applications requiring the greater pressure/temperature capabilities of the other seat materials, it is essential that the appropriate valve build is specified. Examples of these applications include the following: Thermal Fluids (P221 Spec.) Nuclear Service Oxygen Service (Q822 Spec.) Tobacco (Q88 Spec.) Ammonia (Q797 Spec.) Helium (P43 Spec.) Vacuum Service (P43 Spec.) and many more. Flow Coefficients Valve To ensure that the correct valve is supplied, please consult Worcester Controls.

F 44 The F 44 is particularly suitable for hazardous areas in hydrocarbon and chemical process lines, and is anti-static and firesafe to BS 7 Part 2.It is available in stainless or carbon steel from 8 to mm ( 1 ¼4"-2"). 13/14 Worcester Series 13/14 range of three-way valves has been designed for diverting and mixing process media, and features a number of variants which provide a range of operational solutions. HP 44 The HP 44 is Worcester s three-piece ball valve for high pressure hydraulic and gas systems up to 34 Bar ( psi). WK 44 This valve has been specifically developed for use in semi-conductor, pharmaceutical and bio-tech applications. Highly polished internally, the WK 44 has no crevices or bug traps and ensures contamination-free media. SMP 44 Worcester s SMP 44 sample/purge three-piece valve allows steam purging of a process line between batches or for sampling media requiring a high degree of cleanliness from a storage/process vessel. C 44 R7 The C 44 R7 cryogenic valve is suitable for low temperature applications, including CO 2, N 2, Ar, O 2, LNG and other liquid gases.it is available in stainless steel or brass, sizes 8-mm ( 1 ¼4"-2"). AS 44 Worcester s swivel-end connector AS 44 allows for simple orientation and installation of butt welded valves, particularly when long, complicated sections of pre-fabricated pipework are used.
