Standard: JB/T5299
Nominal pressure: PN.025-2.5Mpa
Nominal diameter: DN500 -5000mm
The valve types are al follows:
Common type: HD74 X: simple structure, low cost, counter weight automatic reset to make disk in open
Pressure maintaining type: HD7 4 X: accumulator maintain pressure to make disk in open position
Lockable type: HD7 4 X: pin shaft automatically lock and pull out counter weight in need
Pressure maintaining stable type: HD7 4 X: hydraulic system is five generation product, hydraulic parts such al solenoid valve adopt space technology, use reliable sealing material, no leakage, counter weight does not drop for long period operation, on change of valve opening, stable operating.
