VERSA擁有70多年的經(jīng)驗(yàn)，是閥門(mén)自動(dòng)化和流體動(dòng)力領(lǐng)域的專(zhuān)家。無(wú)論是石油和天然氣，移動(dòng)式氣動(dòng)，散裝裝卸，紙漿和造紙，木工，化工，公用事業(yè)，食品或市政服務(wù)應(yīng)用，VERSA閥門(mén)在世界范圍內(nèi)都被視為質(zhì)量的標(biāo)志。
VERSA閥B900系列介紹
B900 系列由三通 (3/2) 手動(dòng)/先導(dǎo)操作主電源復(fù)位閥和三通 (3/2) 指示繼動(dòng)閥組成。 所有部件均由 316 不銹鋼制成（符合 NACE 標(biāo)準(zhǔn) MR-01-75）。 它們專(zhuān)門(mén)設(shè)計(jì)用于腐蝕性環(huán)境并控制腐蝕性介質(zhì)和空氣。 O 型圈填充提升閥在整個(gè)操作范圍內(nèi)提供氣密密封，當(dāng)用于操作小容量設(shè)備時(shí)，此功能可節(jié)省寶貴的儀表空氣。
主供應(yīng)復(fù)位閥可用作主繼動(dòng)閥，通常是先導(dǎo)式彈簧復(fù)位二位閥，另外還配有手動(dòng)操作裝置。 主供應(yīng)復(fù)位閥的功能是控制向系統(tǒng)或系統(tǒng)部分的壓力供應(yīng)。 如果在系統(tǒng)中的某個(gè)點(diǎn)檢測(cè)到問(wèn)題，主供應(yīng)復(fù)位閥將轉(zhuǎn)換為從主供應(yīng)復(fù)位閥控制的電路部分釋放系統(tǒng)壓力。 主供應(yīng)重置閥的切換是通過(guò)先導(dǎo)裝置完成的，該先導(dǎo)裝置是閥門(mén)的組成部分。 當(dāng)系統(tǒng)正常運(yùn)行時(shí)，先導(dǎo)器會(huì)加壓，但當(dāng)檢測(cè)到問(wèn)題時(shí)，先導(dǎo)器會(huì)減壓，閥門(mén)會(huì)切斷主系統(tǒng)或閥門(mén)控制的主系統(tǒng)部分的壓力。 有多種重置方式可供選擇。 一個(gè)例子是“鎖定先導(dǎo)”，當(dāng)先導(dǎo)壓力返回時(shí)，閥門(mén)不會(huì)移動(dòng)以打開(kāi)主系統(tǒng)的供應(yīng)，直到閥門(mén)被手動(dòng)重置。 復(fù)位的手動(dòng)部分也可以是鎖存的或非鎖存的。 大多數(shù)主供應(yīng)復(fù)位閥還可以配備一個(gè)集成的視覺(jué)指示器，用于指示先導(dǎo)室中何時(shí)存在壓力。 每個(gè)閥門(mén)的完整功能描述可以在該閥門(mén)系列的頁(yè)面上找到。
指示繼動(dòng)閥為先接收或先發(fā)送類(lèi)型。 它們一般有兩個(gè)功能。 首先，在面板上直觀地指示已發(fā)生電路故障；其次，通過(guò)主電源復(fù)位閥快速排出系統(tǒng)中的工作壓力。
The B900 Series is comprised of Three-Way (3/2) Manual/Pilot Operated Main Supply Reset valves and Three-Way (3/2) Indicating Relay valves. All are constructed of 316 stainless steel (meets NACE standard MR-01-75). They are designed for use particularly in corrosive environments and to control aggressive media as well as air. O ring packed poppets provide bubbletight sealing throughout the operating range and when used to operate small volume appliances this feature saves valuable instrument air.
Main Supply Reset valves can function as master relay valves and are generally pilot operated-spring return, 2-position valves that are provided additionally with a means of manual operation. The function of the Main Supply Reset valve is to control the supply of pressure to a system or portion of a system. If a problem is sensed at some point in the system, the Main Supply Reset valve will shift to dump system pressure from that portion of the circuit controlled by that Main Supply Reset valve. The shifting of the Main Supply Reset valve is accomplished by a pilot device which is an integral part of the valve. The pilot is pressurized when the system is running normally, but when a problem is sensed, the pilot is depressurized and the valve shuts off the pressure to the main system or that portion of the main system that the valve controls. Several variations of reset are available. One example is a “l(fā)atching pilot” whereby when pilot pressure returns, the valve will not shift to open the supply to the main system until the valve is manually reset. The manual portion of the reset can also be latching or non-latching. Most Main Supply Reset valves can also be equipped with an integral visual indicator that indicates when pressure is present in the pilot chamber. Complete functional descriptions of each valve can be found on the pages within this valve series.
Indicating Relay valves are of the First Out-Receiving or First Out-Transmitting type. They have two functions generally. First, to indicate visually on a panel that a circuit malfunction has occurred and secondly, to quickly exhaust operating pressure from the system through the Main Supply Reset valve.
