特点
Feature
◆For flourinated refrigerants
◆Resonance problems can be avoided at partial load in the refrigeration plant.
◆Oversize connections provide flexibility in use.
◆Prevents refrigerant from warm to cold system part.
◆Ensures correct flow direction and avoid reversal.
◆Both straightway and angleway versions
◆Built-in damping piston that makes the valves suitable for installation in lines where pulsation can occur,e.g.in the dischange line from the compressor.
◆适用于氟化物制冷剂
◆在部分负荷制冷装置上，共振问题可以避免
◆超大的接口让使用的时候更具灵活性
◆可防止制冷剂从高温蒸发器向低温蒸发器回流。
◆可确保正确的流动防线，防止反冲
◆有直通与直角型两种
◆内置减震垫，使阀门可以安装在压力有脉冲的管路上，比如在压缩机的管路上。
