用于完成一个系统不同回路间的水力平衡。独特的设计结构大大的改变了阀门的流通能力和测量精度。降低了操作难度，提高了调节精度。阀芯采用锥形和软密封结构设计，具有很好的关断和截流能力。DN100以上平衡阀采用分体式结构，上下阀体可旋转，可实现直形和角形安装。
Pren MSV-Z static balancing valve which is made of bronze is applied to the hydraulic balance of duplexure in a system. The 45゜valve handle c***iderably enlarges the currency, which make it easy to install and operate. Besides, the flow measuring accuracy has been largely improved. It helps the engineer in improving the debugging during the process.
功能特点：
常用于供热、制冷水系统中，控制不同环路间的水力平衡。
采用“Y”形阀门结构设计，流量特性好。具有清晰、准确的开度指示。方便调试工作。
***的开关锁定结构。
测压嘴为双“O”形圈密封，并具有自关断防漏水功能。
Features:
Applied in heating/cooling water balancing system, it controls the balance of every different waterways.
The 45゜valve handle c***iderably enlarges the currency, which make it easy to install and debug. Besides, the flow measuring accuracy has been largely improved. It helps the engineer in improving the debugging during the process.
It has functioned of locked up setting.
Double O-ring test nipple, which can automatically shut down if the water leakage happens.
