1 Stage a common choice of valvedesign when smooth flow path, relatively small actuators and long term tight shut-off is desired. > Quick opening(on/off trim) 1, 2, 3 or 4 Stage - the self-cleaning rising disc plug & cage can be provided with a variety of contours to achieve equal %, linear or special flow characteristics. The valves can be delivered as classical on/off angle valves for automated shut off or impulse control. > Cage Trim 1, 2 or 3 Stage - theplug & cage can be provided with a variety of hole drilling design to achieve required flow characteristic and noise attenuation. > Piston Trim used especially when elimination of dead space is a key requirement - such as in polymer applications. >

Choice of Stem Seal single or double packing, bellow seal or purged design are available with TA Luftē certification. Extremely high vacuum version with completely enclosed yoke with Helium leakage under 1x10 Materials Tungsten Carbides, Ceramics, Titanium 5, Duplex, Incoloy or martensitic st.st. are available as options to enhance erosion resistance. > High Pressure Drops - perfectly balanced trimis standard in multistage trim, avoiding the use of large actuators to cover a wide range of pressure drops. > Class V Shutoff Sour Service Capability - use of metal seat to providetight shutoff to...
