UK-C&I-MITECH Globe Control Valves GLOBE CONTROL VALVES The modular, flexible option ABOUT GLOBE CONTROL VALVES The SPIRA-TROL and M-Series Globe Control valves are general purpose control valves that can be engineered to solve both complex and basic requirements. Their robust construction makes them long-lasting and easy to maintain, while their modular design makes them easy to specify, reducing spares inventory requirements. l From standard to severe service l ½” to 16” NB l PN16 to ANSI 2500 l Tight shut-off, low noise, cavitation control, energy dissipating trims INDUSTRIES AND APPLICATIONS l Oil and gas l Chemical l Food l Breweries l Pulp and paper l Power generation THE RANGE AT A GLANCE Valve name Valve type SPIRA-TROL 2-port globe SG iron to ANSI or EN Carbon steel Body materials Valve sizes Connections Flow characteristics Special trims Stem seals Actuation DN15 to DN100 Flanged: ANSI 125 ANSI 150 ANSI 300 Equal percentage Low noise Linear Hard facing Spring loaded chevron and ‘O’ ring Pneumatic diaphragm spring return Graphite Modulating Bellows On / off Stainless steel ½” to 4” Larger Cast iron sizes to NACE order PN16 PN25 PN40 JIS 10 JIS 20 Soft seal Fast opening Reduced flow including microflute Electric Bonnet extension KS 10 KS 20 Screwed: BSP NPT Socket weld M-Series 2-port globe 3-way globe 2-port angle Sweep angle Carbon steel DN15 to Stainless steel DN400 ½” to 16” Bronze Chrome moly Special alloys Severe Service 2-port globe 3-way globe Sweep angle ASME 600 Separable up to 100 NB Equal percentage Low noise PTFE Anti-cavitation Graphite Linear Integral in all sizes Soft seat Bellows Fast opening Pneumatic piston spring return or double acting Pressure balance Live loading Electric Cryogenic Modulating Heat extended On / off Graphite Pneumatic piston spring return or double acting Butt weld Carbon steel DN15 to Stainless steel DN400 ASME 600-4500 Linear ED trims Bi-linear 200:1 turndown Bellows Chrome moly Separable up to 100 NB Tri-linear Pressure balance Special alloys ½” to 16” On request up to 24” Custom made when required Integral in all sizes Electric Butt weld On / off SEVERE SERVICE SPECIAL TRIMS Spirax-Mitech can supply severe service trims to eliminate noise, vibration and cavitation. Applications include oil/gas, refining, power and major process industries. Energy dissipating disk stack. Modulating ation CLAMP IN PLACE, FREE FLOAT DESIGN The entire Spirax-Mitech range of control valves utilises the clamp in place, free float design. All trim components are designed to clamp in place so the valve can be quickly configured to the users specific process needs. The free matic hragm g return float of the seat and plug during assembly means that ric provides the user with longer stem seal life and better ulating stem, plug and seat alignment is easily achieved. When compared to alternative designs, the free float designs valve shut-off performance. off The simplicity of build also means that maintenance is quick and easy, with no special tools required to achieve the design performance of the valve. matic n spring n or le acting ric ulating APPLICATIONS off matic n spring n or le acting ric ulating Angle body choke valve Soot blower valve Recycle and pressure control valve off 4” class 2500 angle valve Crude oil from P1=210 bar to P2=46 bar Tungsten carbide trim 2” class 2500 globe valve Steam at 540ºC from 190 bar to 30 bar 8” class 300 globe valve Oxygen at 112ºC from 36 bar to 1 bar Steam pressure reducing valve Turbine isolation Energy dissipating disk stack 6” x 10” class 2500 x 600 angle valve Steam from P1=98 bar to P2=22 bar Flow = 46700 kg/h Turbine isolation and warm-up station Steam at 430ºC from 46 bar to 1 bar SUMMARY OF KEY FEATURES AND BENEFITS Model Key features Key benefits SPIRA-TROL Precise control Guaranteed control performance across a wide range of applications Universal application Standardised control valve for your plant, which minimises maintenance training and spares inventory High performance long life stem seal Low emissions from the valve stem, which means a better environment and no loss of valuable product or energy Infrequent seal replacement, consequently maintenance personnel are free for other work M-Series Severe Service Long life valve internals Fit and forget Low number of components Highly flexible supply Minimises spares inventory Quick and easy maintenance Limited plant downtime Low cost of ownership Larger profits for you General purpose valve Solves basic and complex requirements Robust construction Long lasting Modular design Reduces spares Suitable for high pressure and extreme temperature conditions Versatile and eliminates noise or cavitation problems Can be adapted for corrosive fluids Versatile Various sizes Versatile Pneumatic, electro-pneumatic or smart positioners Versatile Local CFD design Can be engineered to suit a specific application Linear / bi-linear / tri-linear Suitable for large turndowns (200:1) Wide range of materials Can be engineered to suit a specific application ZZ or disk stack Potential cost reduction on smaller sizes Compact design Suitable for retrofitting er M-SERIES UK-C&I-MITECH SPIRA-TROL SEVERE SERVICE SPIRAX-SARCO LIMITED CHARLTON HOUSE CHELTENHAM GLOUCESTERSHIRE GL53 8ER t: 01242 521361 f: 01242 573342 enquiries@spiraxsarco.com www.spiraxsarco.com/uk © Copyright 2006 Spirax-Sarco Limited Spirax Sarco is a registered trademark of Spirax-Sarco Limited
