Regulators ZSN3 are used to control preset pressure in process installations connected to regulator valve inlet. Regulators are applied in heating systems, in industrial processes with cold and hot water, steam, air and nonflammable gases. Using with other media subject to consulting with manufacturer. CONSTRUCTION:
Regulator comprises three, temporary fastened main units: valve (01), actuator (02) and adjuster (03). Regulator valve single-ported with balanced plug. Flanged connections of valve body with valve face as per PN-EN 1092-1:2006 and PN-EN 1092-2:1999 for PN10; 16; 25; 40 PN-EN 1759-1:2005 for CL150; CL300. Body length as per: PN-EN 60534-3-1:2000 – Series 1 for PN10; 16; 25; 40; Series 37 for CL150; Series 38 for CL300 Valve tightness – bubble (Class VI as per PN-EN 60534-4), tight seat in PTFE or VMQ (ECOSIL). Diaphragm actuator (diaphragm effective area 80 cm2), with clammed housing or diaphragm actuator (diaphragm effective area 160 cm2), with bolted housing.
Control pressure value adjuster with combination of three pre-tensioned springs, fixed coaxially with valve and actuator.
