| ZSH “V” type
control valve for concentrated nitric acid |
|
ZSH “V” type ball valves, developed by Shanghai Fisher Valve, are high performance control valves special for concentrated nitric acid. The valves are little in volume, light in weight, high in adjusting precision and reliable in localizing. The dynamic stability is still good even at opening a little. Using the shear force between the movable seat loaded by plate spring and the core, the valve is suitable to the mediums which contain crystals, scales and little particles. The valve body and core are made of C4 and C6L steel which resist corroding and wearing. The valve seat is made of PTFE. The valves are good in sealing, long in service life and easy in operating.
With “V” gap at the core, there is certain shear force. When the valve opening fully, the flowing capability is big and the resistance is little.
“V” type control valves for concentrated nitric acid are suitable to block 98% concentrated nitric acid with PN1.6～4.0MPa and 40～100℃.
The adjustable rate is 300:1.
Nominal diameter：DN25～400 mm
Nominal pressures：PN1.6、2.5、4.0MPa
