HASS比例閥EPV-500SS產(chǎn)品介紹
Debion
The EPV-500SS Electronic Proportional Valve is a low-cost, computer-controlled proportional valve which directly accepts a 4-20 mA or 1-5V DC control signal. The EPV performs better, costs less to install and less to operate than competitive valves. It is ideal for accurate control of liquid and gas flow.
The EPV has no backlash and no hysteresis. This greatly simplifies control programs. The valve is opened and closed by a zero-backlash screw mechanism. A step motor is directly connected to the valve without gears. The valve can also be operated manually.
An adaptive digital noise filter eliminates dithering of the valve due to noisy control signals. This digital filter can be disabled via a switch on the circuit board.
The valve design features a long-life rotary stem seal. Rotary seals are more durable and require less maintenance than reciprocating stem seals used in pneumatic valves. This seal does not cause the unwanted stick-slip bs of pneumatic valves.
The compact size of the EPV makes it easier to handle, and allows it to be installed in smaller spaces. The EPV is about one-third the size of a pneumatic valve.
An EPV installation costs less than a comparable pneumatic control valve system. There is no need for compressed air, filters, regulators, I-P converters, or pneumatic air lines. Simply connect the EPV to the control signal and the power supply.
The EPV is backed by a five (5) year warranty. The reliable, low-maintenance design and heavy-duty construction reduce costly downtime.
The EPV-500SS is made from Type 316 stainless steel. It has 3/4 inch pipe fittings with a 1/2 port size and a Cv of 3.5.
描述
EPV-500SS 電子比例閥是一種低成本的計(jì)算機(jī)控制比例閥，可直接接受 4-20 mA 或 1-5V DC 控制信號(hào)。與競(jìng)爭(zhēng)閥門相比，EPV 性能更好，安裝成本更低，運(yùn)行成本更低。它是精確控制液體和氣體流量的理想選擇。
EPV 沒(méi)有反沖和滯后。這大大簡(jiǎn)化了控制程序。閥門通過(guò)零背隙螺桿機(jī)構(gòu)打開(kāi)和關(guān)閉。步進(jìn)電機(jī)直接連接到閥門，無(wú)需齒輪。閥門也可以手動(dòng)操作。
自適應(yīng)數(shù)字噪聲濾波器消除了由于噪聲控制信號(hào)引起的閥門抖動(dòng)。該數(shù)字濾波器可以通過(guò)電路板上的開(kāi)關(guān)禁用。
閥門設(shè)計(jì)具有長(zhǎng)壽命的旋轉(zhuǎn)閥桿密封。與氣動(dòng)閥中使用的往復(fù)式閥桿密封件相比，旋轉(zhuǎn)密封件更耐用且需要更少的維護(hù)。這種密封不會(huì)導(dǎo)致氣動(dòng)閥產(chǎn)生不必要的粘滑動(dòng)作。
EPV 的緊湊尺寸使其更易于操作，并且可以安裝在更小的空間內(nèi)。 EPV 的尺寸約為氣動(dòng)閥的三分之一。
EPV 安裝成本低于類似的氣動(dòng)控制閥系統(tǒng)。無(wú)需壓縮空氣、過(guò)濾器、調(diào)節(jié)器、I-P 轉(zhuǎn)換器或氣動(dòng)空氣管路。只需將 EPV 連接到控制信號(hào)和電源。
EPV 享有五 (5) 年保修?？煽俊⒌途S護(hù)的設(shè)計(jì)和重型結(jié)構(gòu)減少了代價(jià)高昂的停機(jī)時(shí)間。
EPV-500SS 由 316 型不銹鋼制成。它具有 3/4 英寸管件，端口尺寸為 1/2，Cv 為 3.5。
