截止閥性能優(yōu)勢(shì):
1. 閥體采用精密鑄造工藝,先進(jìn)的工藝了確保閥體無(wú)砂眼,表現(xiàn)光滑,質(zhì)量更可靠。
The valve body adopts investment casting technology. Advanced technology to ensure that the valve body has no sand holes, surface more smooth and quality more reliable.
2. 上密封結(jié)構(gòu),當(dāng)閥門全開時(shí),上密封結(jié)構(gòu)將起到額外的密封作用,具有行程定位和抗振功能。
Back seat structure. In the fully open position, back seat will form a extra sealing, with stroke locate and anti-vibration function.
3. 堆焊閥座,即使在惡劣工況下,也能確??煽康拿芊?。
Overlay welded seat can keep reliable sealing under severe conditions.
4. 人體工程學(xué)設(shè)計(jì)手輪,使用壽命更長(zhǎng),操作輕松便捷且安全可靠。
Ergonomic hand wheel. It provide longer service life and easier Operation.
