Bivco 止回阀 0 至 120 psig (77)

Bivco Check Valve 0 to 120 psig (77)

特点和优点

• 无泄漏

即使在低压差下也能提供气密密封。

• 低压降

大通道提供流动特性，压降低于竞争阀门。

• 不粘

自由浮动阀座和阀芯设计可防止因阀盘部件倾斜而导致的粘连。阀座和阀芯中使用的 PTFE 具有自润滑性和耐腐蚀性。

Features and Benefits

• No Leakage

Bubble-tight sealing is provided even at low-pressure differentials.

• Low Pressure Drop

Large passgeways provided flow chararcteristics with lower pressure drop than competing valves.

• Non-Sticking

The free-floating seat and poppet design prevents sticking due to canting of the disk member. PTFE used in seats and poppets is self lubricating and resistant to corrosion.
