A butterfly valve a nichu valve chhungkaw pakhat atanga lo chhuak a ni a, chu chuquarter-turn valve te a awm bawk. Operation-ah chuan disc chu quarter turn-a a inher chuan valve chu a inhawng kim emaw, a khar vek emaw a ni. “Butterfly” chu thir disc, rod-a dah a ni. Valve khar a nih chuan disc chu a turn off a, chu chuan passageway chu a block vek a ni. Valve chu a inhawng kim chuan disc chu quarter turn-in an inher a, chutiang chuan fluid chu khap lo deuh maiin a kal thei a ni. Valve hi throttle flow turin incrementally hawn theih a ni bawk.

Butterfly valve chi hrang hrang a awm a, pressure hrang hrang leh hman dan hrang hranga siam a ni. Rubber flexibility hmanga siam zero-offset butterfly valve hian pressure rating a nei hniam ber a ni. High-performance double offset butterfly valve, pressure sang deuh system-a hman thin hi disc seat leh body seal center line (offset pakhat), leh bore center line (offset pahnih) atanga offset a ni. Hei hian operation laiin cam action a siam a, seat chu seal atanga chhuah tir a, chu chuan zero offset design-a siam aiin friction a ti tlem zawk a, a wear duhna a ti tlem bawk. High-pressure system atana valve tha ber chu triple offset butterfly valve hi a ni. He valve ah hian disc seat contact axis chu offset a ni a, hei hian disc leh seat inkara sliding contact chu a ti bo vek a ni. Triple offset valve-ah chuan seat hi metal a siam a ni a, chutiang chuan disc nena inzawm chuan bubble tight shut-off a awm theih nan machine hmanga siam theih a ni.

Type hrang hrang

1. Concentric butterfly valve hmanga siam a ni– he valve chi hian rubber seat resilient tak, metal disc nei a nei a.
2. A rilru a buai em em a, a rilru a hah em em bawk a(high-performance butterfly valve emaw double-offset butterfly valve emaw) – seat leh disc atan hian thil chi hrang hrang hman a ni.
3. Triply-eccentric tak tak, butterfly valve te chu a awm a(triple-offset butterfly valves) – seat te hi laminated emaw solid metal seat design emaw a ni.

Wafer ang chi butterfly valve hmanga siam a ni

Chumiwafer style-a butterfly valve hmanga siam a nichu unidirectional flow atana siam system-a backflow awm lo turin bi-directional pressure differential laka seal vawng reng tura duan a ni. Chu chu seal nghet tak hmangin a tihlawhtling a; chu chu gasket, o-ring, precision machined, leh valve chunglam leh hnuai lam a valve hmai flat tak a ni.

Lug-style butterfly valve hmanga siam a ni

Lug-style valve hmanga siam a nivalve body sir lehlamah threaded insert nei rawh. Hei hian bolt set hnih hmangin system pakhatah dah theih a ni a, nut pawh a awm lo. Valve hi flange pahnih inkarah flange tin tan bolt set hran hmangin dah a ni. He setup hian piping system sir lehlamah tibuai lovin a sir lehlamah a titawp thei a ni.

Dead end service-a hman thin lug-style butterfly valve hian a tlangpuiin pressure rating a tihhniam a ni. Entirnan, flange pahnih inkar a lug-style butterfly valve dah hian 1,000 kPa (150 psi) pressure rating a nei a. Flange pakhata dah valve ang chiah, dead end service-ah chuan 520 kPa (75 psi) rating a nei a ni. Lugged valve hi chemical leh solvent lakah a do thei hle a, 200 °C thlenga temperature a tuar thei a, hei hian solution versatile tak a ni.

Industry-a hman tur

Damdawi siamna, chemical leh ei tur siamna lamah chuan butterfly valve hmangin a chhunga thil siam chhuah (solid, liquid, gas) chu a titawp thin. Heng industry-a valve hman te hi cGMP guidelines (tuna siam dan tha tak) angin siam a ni tlangpui. Industry tam takah, a bik takin petroleum-ah chuan butterfly valve hian ball valve a thlak tlangpui a, hei hi a man tlawm zawk leh dah awlsam vang a ni a, mahse butterfly valve awmna pipeline-te chu tihfai nan ‘pigged’ theih a ni lo.
