No. LRQ 9638 ISO 91 SPIR-TROL DN15 to DN1 K, KF and KL Two-port Control Valves TI-P374-1 C Issue 2 Description SPIR-TROL is a range of two-port single seat globe valves with cage retained seats conforming to N standard. These valves are available in three body materials in sizes ranging from DN15 to DN1. When used in conjunction with a pneumatic or electric linear actuator they provide modulating control or on / off service. SPIR-TROL valve characteristic - options: K qual percentage () - Suitable for most modulating process control applications providing good control at all flowrates. KF Fast opening (F) - For on / off applications only. KL Linear (L) - Primarily for liquid flow control where the differential pressures across the valve is constant. Important note: Throughout this document, reference has been made to the standard K control valve. With the exception of trim type, the K, KF and KL control valves are identical. SPIR-TROL valve options: PTF chevron seals Standard ellows / PTF () Suitable for thermal fluids Stem sealing ellows / graphite (C) Suitable for thermal fluids ellows / graphite Zero emissions and high temperature secondary seals (D) applications Graphite packing igh temperature applications Metal-to-metal 431 stainless steel - standard 316L stainless steel Seating Up to 2 C - PTF for Class VI shut-off Soft seating Up to 25 C - PTF for Class VI shut-off ard facing 316L stainless steel with Stellite 6 facing - for more arduous applications onnet Standard bonnet type xtended bonnet for large pipe lagging or hot / cold applications Trim Standard trim Low noise cage SPIR-TROL two-port control valves are compatible with the following actuators and positioners: lectric L35, L56 and L72 series Pneumatic PN1 and PN9 series PP5 (pneumatic) or P5 (electropneumatic) ISP5 (intrinsically safe electropneumatic) Positioners SP2is, SP4, and SP5 (microprocessor based electropneumatic) SP3 (digital communications) Refer to the relevant Technical Information sheet for further details.
