Globe valve Z1B-M

manualweldedfor pump

Minimum flow valves are designed for use in recirculation systems of pumps supplying power boilers. They protect the pumps against hydraulic and thermal overload in case of low water consumption by the boiler, ensuring minimum flow in the bypass circuit of the pump (by-pass). The valve type Z1B-M thanks to its construction, selection of materials and technology is a valve adapted to use in the most difficult working conditions, at a high pressure drop and risk of cavitation. In the presented version, it can be used as a minimum flow valve in bypass systems (by-pass) of pumps supplying power boilers. We can adjust the control valve to match your individual needs. Connections - for welding ∅76x13,other types of connection – upon request Leakage class: - V class acc. to PN-EN 60534-4. Direction of flow: - above the plug Flow rate: - Kvs 7, 10, 16, 20 Characteristics: - linear high tightness of closing, guaranteed external tightness, seals according to TA Luft regulations in the low pressure zone, easy access to internal elements of the valve, control or on-off function, possibility to use pneumatic, hydraulic or electric drives, wide range of designs, possibility to adapt the valve to individual customer requirements in terms of connections, flow parameters and others, additional equipment: quick release valve for pneumatic actuators (quick opening), spring damper for hydraulic or electric actuators (flexible plug pressure to seat), resistance to hydraulic impacts (water hammer), high durability and reliability of operation.
