3 GRETEST SFETY Relialy sealed IVERSITY Regulating valve TE SEING SYSTEM The sealing element of the piston valve is formed y a stainless steel piston, which is enclosed y two valve rings. In this configuration, the upper valve ring ensures tightness to the atmosphere, while the lower ring relialy provides sealing in the ore. The large surface of the valve rings leads to optimal sealing. In order to allow for easy actuation in the event of high differential pressure, the pistons in the series VIII, 65 to 200, are produced with a pressure-alanced design. Upon closing of the valve, the piston pushes contaminants which may e present in the medium, away from the inner side of the valve ring. s a consequence, even contaminated media can e relialy sealed off, preventing damage to the sealing surface. The high-quality KX-GT valve rings, which consist of graphite laminate with layers of stainless steel metal are ideally suited for temperature shock as well as steam condensate-alternating operation. Various thermal expansions caused y alternating thermal loads are fully compensated y the pre-sealed KX-GT valve rings. KINGER piston valves are ideal for control purposes. For nominal sizes of 15 to 50, a regulating piston is utilized. lantern ush is used for nominal sizes etween 65 and 200. The regulating piston and the lantern ush oth feature a curved geometry, which results in a nearly linear flow line. Thanks to the identical sealing system, the shut-off function is also guaranteed in the ore. Furthermore, this design makes it possile to convert the into a regulating valve at any given time y simply exchanging the piston or the lantern kv value [m³/h] (Standard ) andwheel rotation COSE kv value [m³/h] KVRN 100 (Regulating design) andwheel rotation COSE 06 07

11 TECNIC ETIS ctuator design UTOMTION Optimization and precision KINGER piston valves can e automated y means of electrical and pneumatic actuators. Multiple designs with an ISO flange can e utilized for automation y means of an electrical actuator. The pneumatic memrane actuator, on the other hand, is directly mounted and is availale in a simple or doule-acting design. When selecting the actuator, ensure that the actuator is specified with a torque rating corresponding to the nominal size.» with mounted actuator vailale either with an electromechanical or a pneumatic actuator.» Electromechanical actuator vailale for 400 Volt and 230 Volt respectively as well as with special voltage on demand. Torques Nominal size Pressure differential Torque mm ar Nm KINGER Fluid Control recommends the factor 1.5, i.e. using plus 50 % for standard computations. Flow values (mm) K vs -values » Pneumatic actuator The pneumatic memrane actuator can e provided in a single as well as in a doule-acting design and offers an OPEN/COSE function. The single-acting actuator is executed in a manner that allows the valve to e closed y means of spring tension and opened y means of set pressure. The characteristic unit for shut-off and control valves in the metric system is the Kv-value. The values provided in the tale apply to the 2O flow medium with a temperature of 5 30 C, a density of 1000 kg/m 3 and a pressure loss of p = 1 ar at the valve. In countries using inches, the characteristic unit is the Cv-value. It provides how many US gal/min of 2O, at a temperature of 60 F and with a pressure loss of 1 psi, flow through the valve. Flow rate Pressure loss ensity Velocity Flow coefficient Pressure loss coefficient Q p w K v in m 3 /h in ar in kg/m 3 in m/s in m 3 /h llows for the calculation of: K v = Q * 1000 * p or 2 * p = * 10 5 * w 2 The valve is to e selected in a manner that the Kv-value is greater, or the -value less than the computed value for the desired application.
