日本阀天RD-14H减压阀，VENN减压阀，RD-14H减压阀详细描述：
RD-14H valve is suitable for: oil, pressure 1.0Mpa following caliber range: 20-150mm Suitable temperature: 5-90 ℃ Body material: cast iron valves day Japan RD-14H is by adjusting the valve, the inlet pressure is reduced to the outlet pressure of a need, and rely on the energy of the medium itself, so that automatically maintain a stable outlet pressure valve.

RD-14H减压阀适用于：压力1.0Mpa以下的油品，口径范围：20-150mm 适用温度：5-90℃ 阀体材质为：铸铁 日本阀天RD-14H减压阀是通过调节，将进口压力减至某一需要的出口压力，并依靠介质本身的能量，使出口压力自动保持稳定的阀门。
Operation:
1, closed gate valve before the open gate valve after low pressure downstream manufacturing environment;
2, the adjusting screw counterclockwise rotation to the uppermost position (relative to the minimum outlet pressure), and then close the valve after the valve;
3. Slowly open the gate valve to fully open before;
4. Slowly turn adjustment screw clockwise, the pressure is adjusted to the desired outlet pressure (gauge pressure in the valve prevail); adjusted, the lock
Nut, open the valve gate valve;
5, such as export when adjusting the pressure higher than the set pressure, must start from the first step to re-adjust, which can only tune from low to high pressure.
日本阀天RD-14H减压阀操作方式：
1、关闭减压阀前的闸阀，开启减压阀后的闸阀，制造下游低压环境；
2、将调节螺钉按逆时针旋转至zui上位置（相对zui低出口压力），然后关闭减压阀后闸阀；
3、慢慢开启减压阀前的闸阀至全开；
4、顺时针慢慢旋转调节螺钉，将出口压力调至所需要的压力（以阀后表压为准）；调整好后，将锁紧
螺母锁紧，打开减压阀后闸阀；
5、如在调整时出口压力高于设定压力，须从*步开始重新调整，即只能从低压向高压调。
