Product Description

1. purpose Used in the systems of drainage , can rapid response and quickly release to the pressure waves to prevent a sharp increase in pressure damaging pipes and equipments, and can also be used to protect the main valve o f providing water. 2. Characteristic a). Accurate in constantly keeping pressure secure and stable once over the pressure, the Relief Valve can fully open to relief pressure timely . b). Adjustable closing speed, eliminating pressure fluctuations; c). Diaphragm driving mechanism can minimize the lag operator; d). Can be installed in any location, without changing the pressure setting or be removed from the pipeline for maintenance; e). Sensitive and reliable, small frictional resistance. 3. the technical parameter a). Nominal pressure: 1.0 1.6 2.5 Mpa b). Adjustment range: 0.**0.9MPa; 0.**1.4MPa; 0.**2.2MPa c). Operating pressure: 0.*5MPa d). Applicable temperature :***0 ℃ e). Applicable media: water, oil
