| 116-31 (截止阀) / 1116-31 (角阀)
减压平衡阀 / 电磁阀开-关
116-31 (Globe) / 1116-31 (Angle)
PRESSURE SUSTAINING / SOLENOID ON-OFF
安装在主管线内，防止上游压力降到预置最小压力以下。电磁阀的过载平衡功能使其能够进行电气开-关操作。
Installed in a mainline it prevents upstream pressure
from dropping below a preset minimum. Solenoid override of the sustaining
function allows for electrical on-off operation.
注：
调节范围：
标准：20-200 psig
选项：0-30 psig,100-300 psig
电磁阀最大工作压力：在订购时，请告知实际系统工作压力，以便工厂对电磁阀正确选型。（如果压力超过150 psig，请咨询工厂）。
外壳保护标准：NEMA 1, 2, 3, 3S, 4, 4X
选项：防爆NEMA 3, 3S, 4, 4X, 6, 6P, 7, 9
请具体说明通电时开启主阀还是通电时关闭主阀
NOTE:
Adjustment range:
Standard: 20-200 psig
Optional: 0-30 psig,100-300 psig
Solenoid max. W.P.: At time of order, advise factory actual system working
pressure for correct solenoid selection. (consult factory if over 150
psig.)
Enclosure: NEMA 1, 2, 3, 3S, 4, 4X
Optional: Explosion proof NEMA 3, 3S, 4, 4X, 6, 6P, 7, 9
Specify energized to open or energized to close main valve.
快速选型：阀门通径与管线口径相同。
QUICK SIZING: Valve
size same size as line.

阀门性能
VALVE FUNCTION
- 通过释放过高的压力来保持恒定的上游压力（进入阀门）
Maintain constant upstream pressure (inlet
to valve) by relieving excess pressure
- 电磁阀提供释压/平衡过载的电气开-关性能
Solenoid provides electrical on/off override
of relief/sustaining function
