False 2- way Control Valves type L1S2.2.02- K Gun Metal, PN 16, DN 15/ 6 – 20 mmGB- 1 Technical Data Materials: - valve body Gun metal RG 5 - components Stainless steel Nominal pressure PN 16 Seating Single seated Valve characteristic Quadratic Leakage = 0.05% of kvs Temperature range See pressure/ tem-perature diagram Mounting See page 2 Internal connection threads ISO 7/ 1 Subject to change without notice. Characteristics • Nominal pressure PN 16 • Regulating capability • Single seated and tight closing • Quadratic characteristic Applications Regulating valves type L1S are designed for regulating low, medium and high pressure hot water, steam and lubricating oils. The valves are installed combined with temperature or pressure differential regulators in control systems for heating of domestic premises, district heating, industrial processes or marine installa-tions. Dimensioning For sizing of control valves and selection of actuators please see " Quick Choice" leafl et no. 9.0.00. Design The valve components - spindle, seats and cone - are made of stainless steel. The valve body is made of gun metal RG 5. The thread for the actuator con-nection is G1B ISO 228. The valves are single seated and designed for tight closure. The leakage rate is less than 0.05% of the full fl ow ( according to VDI/ VDE 2174). To obtain an approximate, linear transfer performance, for use in systems with standard existing heat exchangers and pumps, the valve characteristic is made quadratic. Quality assurance All valves are manufactured under an ISO 9001 certifi cation, and are pressure and leakage tested before shipment. For marine applications the valves can be supplied with relevant test certifi cates from recognized classifi cation societies. Function Without the actuator being connected, the valve is held in open position by means of a spring. With pressure on the spindle the valve will close. In connection with thermostats or elec-tronic actuators, the valves will close at rising temperatures. For cooling circuits a reverse acting valve can be used. The quadratic characteristic will not cease, until the fl ow has dropped below 4% of the full fl ow.

False 2- way Control Valves type L1S Gun Metal, PN 16, DN 15/ 6 – 20 mmGB- 2 2.2.02- K Defi nition of kvs- value The kvs- value is identical to the IEC fl ow coeffi cient kv and defi ned as the water fl ow rate in m3/ h through the fully open valve by a constant differential pressure, ?pv, of 1 bar. Mounting The valves can be installed with vertical as well as horizontal spindles. For valve temperatures of max. 170 º C, the thermo-stat/ actuator can be fi tted below or above the valve. For valve temperatures above 170 º C, a cooling unit of type KS 4 has to be applied with connection downwards. Strainer It is recommended to use a strainer in front of the regulating valve if the liquid contains suspended particles. Dimension sketch ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ?? ??
