Siebe offers exceptionally rugged industrial globe valves for liquid, gas, and vapor applications.  Superior body design allows for increased Cv values while minimizing cavitation and flashing. Broad range of Cv values from microseat to full port in each line size. Shaft and stem guided plugs as well as contoured cage guided plugs in balanced and unbalanced designs to meet various process application requirements. Bonnets available for cryogenic and high temperature applications. Bellows seals for hazardous, toxic, and lethal service, and live-loaded packing for maintenance-free stem seal. Exclusive standard certified stem packing provides equivalent to bellows seal leak protection. Broad selection of standard and specialty trims. Low noise option available that can be installed in the field.
The FoxFlex™ rotary globe valve is used in almost every industrial sector.  It incorporates many innovations such as an intregral positioner into the actuator and a field adjustable rated Cv.  It offers maximum flexibility in terms of material and configuration. One-piece valve body no static or dynamic seal except stuffing box. No breakaway-torque due to patent-pending seat-plug geometry. Best control performance due to low=friction rolling diaphragm actuator. Rated Cv adjustable in process without exchange of seat ring or plug and without disassembly of actuator. Positioner system fully integrated into actuator housing. Protects against damage. Purges all internals with instrument air thus protecting against condensate and corrosion. Optional limit switches integrated into actuator housing. Universal applicability due to a wide range of flange connections, face to face dimensions and body and trim materials. Exceptional price/performance ration.
A versatile line of high-performance valves for general purpose applications and where lighter duty, lower maintenance, and larger line sizes are appropriate.  Economical to install and apply, butterfly valves provide continued savings throughout their operating life. Resilient and metal seating available to meet all process requirements. Self-centering or one-piece disk and stem to meet all application requirements. Variety of linings and disk material for expanded application suitability.
Ball valves are particularly suited to automated on/off and control applications or when unrestricted full-line flow is important. Full range of material selection. Most positive shut-off of any control valve type. Inherent equal percentage characteristics, but can be modified thorough our digital positioner to match process requirements. Economical choice for many applications.
Siebe complements its mainstream valves with a variety of specialty valves designed to handle unique process situations. Diaphragm types accommodate heavy entrained solid fluids such as slurries and pulp stock.  Well suited to very corrosive processes. Sanitary types provide quick-connections and CIP design. Three-way valves provide convenient diverter and blending capability. Steam let down types for boiler applications. PTFE-lined globe valves for corrosive fluids. Check valves available in a variety of exotic alloys.
