Performance requirements for flow control valve of four-column hydraulic press

Performance requirements for flow control valve of four-column hydraulic press

1 When the pressure difference before and after the throttle valve of the four-column hydraulic press changes, the flow rate through the valve changes.

2. When the oil temperature changes and the freshness of the oil changes in the four-column hydraulic press, the change in the flow rate through the throttle valve should be small (usually O.

05~O.l~/min).

3 The orifice should not be easily blocked, so that the throttle valve can obtain a lower minimum stability

flow.

4. The pressure loss of the four-column hydraulic press through the orifice should be tied (generally should be less than 0.3MPa).

5. The throttle valve of the four-column hydraulic press should be adjusted flexibly and evenly.

6 When the throttle valve is closed, the leakage should be as small as 4 (generally should be less than 0 to 0.03L/min). This article comes from the hydraulic manufacturer WORLD Press Machine official website www.pressmachine-world.com, please indicate the source for reprinting!
