LANDEFELD逆流阀USV12-8产品介绍

LANDEFELD逆流阀USV12-8产品介绍

版本：

使用内六角扳手可以在操作条件下调整安全阀，而不会将任何介质释放到周围环境中。不提供背压补偿。

材料：

阀体：红铜/黄铜，弹簧：不锈钢，密封：FKM（设定压力12至20 bar：PTFE）

温度范围：

-20 至 +200 °C

介质：

压缩空气和其他具有腐蚀性的不燃气体，水和其他中性、无毒液体，矿物油

可选项：

阀体由不锈钢1.4401/1.4408制成 -ES

优势：  

紧凑的设计

自给自足的气密设计

优化的高Kv值

可在不拆卸且无需专业工具的情况下进行外部调整

广泛的压力范围覆盖

可用于气体和液体介质

应用：

安全阀用于闭环系统中以保护泵免于过载。当可调反应压力被超过时，阀门按照超压比例开启，从而缓慢释放压力。安全阀设计为长时间保持开启状态。原则上必须假设系统中的压力可能超过安全阀设定的反应压力。

安全阀具有完全不同的响应特性。如果反应压力超过10%以上，它们会几乎瞬间打开并一次性释放所有压力。当压力降低到设定反应压力的10-20%以下时，阀门再次关闭。尽管此功能确实可以确保设定压力不会超过10%以上，但系统会因非比例的开启行为而承受较大压力。

Version:

Using an Allen key, the relief valves can be adjusted under operating conditions, and without releasing any medium into the surroundings. You are not compensated against back pressure.

Materials:

Body: Gunmetal / brass, spring: stainless steel, seal: FKM (set pressure 12 to 20 bar: PTFE)

Temperature range:

-20 to +200 °C

Media:

Compressed air and other aggressive, non-flammable gases, water and other neutral, non-toxic fluids, mineral oils

Optional:

Body made of stainless steel 1.4401/1.4408 -ES

Advantages:

•compact design,

•self-contained gas-tight design,

•optimised with high Kv values,

•can be adjusted externally without disassembly and without special tools,

•wide pressure range coverable with a valve,

•can be used for gas-forming and liquid media

Application:

Relief valves are used in closed circuits to protect pumps from overload. When the adjustable reaction pressure is exceeded, the valve opens in proportion to the overpressure and thus slowly releases pressure. The relief valve is designed to be open for an extended time. As a matter of principle, one must assume that the pressure in the system can exceed the reaction pressure set on the relief valve.

Safety valves have a completely different response characteristic. In the event that the reaction pressure is exceeded by more than 10%, they open almost instantaneously and release all pressure at once. When the pressure comes down to 10-20% below the set reaction pressure, the valve closes again.

Although this function does ensure that the set pressure will not be exceeded by more than 10%, the system will be heavily stressed by the non-proportional opening behaviour.
