OPW 61SO型卸油防溢閥
OPW 61SO Overfill Prevention Valves
OPW 61SO型是一種兩級封閉的防溢閥，主動切斷油品的輸入以防止油品溢出油罐，防止污染環(huán)境和產(chǎn)生危險。61SO型設(shè)計僅用在密閉重力卸油，它能安裝在新的和現(xiàn)有地下油罐的立管上，61SO安裝簡單，不需破壞混凝土，不需特殊的人孔。61SO型具備多種型號以適用任何地下油罐，包括：兩點式，同軸式，提動同軸式，遠(yuǎn)端卸油式。
OPW61SO型是兩級封閉的防溢閥。當(dāng)油品升至油罐容量的大約95％時，防溢閥的機械裝置釋放，自動關(guān)閉卸油。此時通過一個分流管減少流速至大約5GPM。操作員然后可以停止卸油，切斷以及排空卸油軟管。每次當(dāng)油品超過油罐容量的95％時，卸油閥們就會自動關(guān)閉。如果沒有停止卸油而且油品超過油罐容量的98％時，分流閥將完全關(guān)閉。直到油面降至復(fù)位點下，不會有油品流進(jìn)油罐中。
OPW 61SO Overfill Prevention Valve
OPW 61SO不同型號可滿足各種地下油罐的應(yīng)用，包括：兩點式，同軸式，提動軸式，遠(yuǎn)端卸油式。61SO和卸油管道可以用螺紋或法蘭連接，以保證卸油防溢閥安裝在和適的位置，安全關(guān)閉卸油管。
OPW 61SO型卸油防溢閥特點：
簡單，容易和快速安裝：無需發(fā)掘和特殊的人孔。
經(jīng)濟節(jié)約：花費為其他昂貴、復(fù)雜和難于安裝的閥門的一小部分。
裝備完善： 提供全新的上部和下部豎直管道，安裝工具和完整的手冊，便于減少現(xiàn)場工作時間。
完全自動操作：無需預(yù)先檢查操作，無需復(fù)位，不會中斷或者濫用。
不會對油罐產(chǎn)生壓力，直接由油品液面控制�？梢允褂昧坑统邷y量油品液面
直接迅速改進(jìn)：適用于配有3”/4”卸油立管的新舊油罐。
快速排空的特點，當(dāng)頂部壓力釋放時，自動排空油喉。
工業(yè)界最佳流速。
OPW 61SO防溢卸油閥的優(yōu)點：
和溢出警告系統(tǒng)的比較完善的自動控制：不需依賴卸油工警戒性和反應(yīng)速度來保證防溢。
按照EPA要求保持地下油罐頂端干燥：消除由松動的油喉配件而引起的滲漏和對雙層排空管的要求。
不許依靠地下油罐內(nèi)的壓力來停止卸油：減少卸油時間和淺灑的危險。
卸油快速：油品可順利進(jìn)入油罐，直到液面達(dá)到關(guān)閉位置時油喉啟動關(guān)閉功能。
簡單的和低價安裝：不論兩點式和同軸式卸油裝置，不需額外的挖掘、人空和排空管的改造。
OPW 61SO型卸油防溢閥材料：
閥門主體：澆鑄鋁
密封條：氟橡膠
浮子：腈橡膠，網(wǎng)格泡沫
上部下部卸油管道：鋁
閥門：鋁
塑料部分：乙縮醛
螺絲及工具：不銹鋼
重要提示：
為了防止油品從地下油箱中溢出，適當(dāng)?shù)鼐S修卸油置和保證快速接頭的聯(lián)結(jié)是必要的。卸油員工應(yīng)該經(jīng)過管理和培訓(xùn)，檢查卸油彎管和軟管的損壞和零件遺失。他們應(yīng)該經(jīng)常確定快速接頭和軟管之間的正確連接。如果卸油裝置沒有適當(dāng)?shù)木S護(hù)或者彎管沒有緊密連接到快速接頭，當(dāng)OPW61SO型關(guān)閉時會發(fā)生嚴(yán)重的溢出，并引起一個危險和環(huán)境的問題
注：OPW61SO型只能用在重力下落式卸油器件中，不能用在壓力填塞卸油器件中。

61SO Overfill Prevention Valves
The OPW 61SO Overfill Prevention Valve is designed to prevent the overfill of underground storage tanks by providing a positive shut-off of product delivery. The shut-off valve is an integral part of the drop tube used for gravity filling. The OPW 61SO allows easy installation (without breaking concrete) and requires no special manholes.
The OPW 61SO is a two-stage shut-off valve. When the liquid level rises to about 95% of tank capacity, the valve mechanism is released, closing automatically with the flow. This reduces the flow rate to approximately 5 gpm through a bypass valve. The operator may then stop the filling process and disconnect and drain the delivery hose. As long as the liquid exceeds the 95% level, the valve will close automatically each time delivery is attempted.
If the delivery is not stopped and the liquid rises to about 98% of tank capacity, the bypass valve closes completely. No additional liquid can flow into the tank until the level drops below a reset point.
The 61SO Overfill Prevention Valve can be adjusted to shutoff at any desired tank capacity. Please contact the Authority Having Jurisdiction (AHJ) and review local, state, and national codes to determine the regulatory requirements governing shut-off capacity in your region, as well as take into account other considerations such as extreme tank tilt. In all cases, the upper tube must protrude into the tank at least 6-1/2" to ensure that the valve can shut off flow into the tank completely before the top of the tank is wetted as per EPA requirements.
Models of the 61SO are available to meet virtually any UST application including two-point, coaxial, poppeted coaxial and remote fill. Methanol approved models are also available.

61SOR Remote-Fill
The OPW 61SOR is designed for two-point remote-fill applications, where the fill point is not directly over the UST. The valve is installed in the tank through a riser pipe directly over the tank. A window in the drop tube is aligned with the entrance of the fill pipe from the remote-fill location to allow product to flow into the drop tube and down through the valve. A riser seal prevents product from flowing into the tank from outside the drop tube. A “trap door” assembly installed in the riser above the tank provides access for a gauging stick. Trap door, adaptor and cap are included with 61SOR.
61SOR Remote Fill Tube Instruction Sheet Order Number: H11964M
61SOC Coaxial
The OPW 61SOC is used for coaxial fill applications, tanks equipped with a single product/vapor return connection. The 61SOC replaces the standard coaxial fill drop tube in a 4" riser fill pipe.

61SOC Coaxial Fill Tube Instruction Sheet Order Number: C03634PA
71SO Vapor-Tight Remote Fill
The OPW Vapor-Tight Remote Fill is designed for two-point vapor-tight remote-fill applications, where the fill point is not directly over the UST. A CARB approved vapor-tight 61SO overfill valve is installed in the sump through a riser pipe directly over the tank. The 61JSK-4RMT Kit installed within a 4” Tee provides an anchoring mechanism by locking the 61SO overfill valve in the tank fill riser. The “trap-door” assembly installed in the riser above the tank retains access for a gauge stick. The 61JSK-4RMT Kit coupled with any Vapor-Tight 61SO Overfill Valve will work for this application.
OPW Overfill Prevention Valves are designed to prevent the overfill of USTs by providing a positive shut-off of product delivery.
