FaqS

He aha kaʻokoʻa ma waena o kahi wafer a me ka life-style butterfly valvefly?

Wafer valves clamp ma waena o nā flanges (ʻaʻohe lua bolt), ʻOiaiʻo nā lole holoi holoi i nā ligs i kauʻia no ka hoʻonohonohoʻana, aeʻae ana i ka hoʻokaʻawaleʻana. Lug valves kūpono kūpono (Çhod52 Bar) ʻoi aku ka maʻalahi (≤16).

Pehea ka lōʻihi o nā butterfly valves?

ʻO nā ola ola no nā makahiki he 10-15 no nā mea kūʻai aku e noho ai nā mea kūʻai aku i nāʻoihana maʻemaʻe e pili ana i nāʻano he 5-8 no nā mea kūʻai aku ma nā wahi e noho ai. Hoʻonui ka mālama ponoʻana i ke ola ma ka 30-50%.

ʻO nā mea momona he kūpono kūpono no ka slurry a iʻole nā ​​wai abrasive?

He kūpono nā Vericats Triple-Seet; resilite ceats erode wikiwiki. E hoʻohana i nā mea paʻakikī paʻakikī (E.g., ʻO ka kila kila fuplex) no ka lole i hala.
