HASS比例閥EPV-500B產(chǎn)品介紹
EPV-500B 電子比例閥是一種低成本、計(jì)算機(jī)控制的比例閥，可直接接受 4-20 mA 或 1-5V 直流控制信號(hào)。 與競(jìng)爭(zhēng)閥門(mén)相比，EPV 性能更好，安裝成本和操作成本更低。 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(mén)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(mén)，無(wú)需齒輪。 閥門(mén)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(mén)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(mén)設(shè)計(jì)采用長(zhǎng)壽命旋轉(zhuǎn)閥桿密封。 與氣動(dòng)閥中使用的往復(fù)式閥桿密封相比，旋轉(zhuǎn)密封更耐用且需要更少的維護(hù)。 這種密封不會(huì)引起氣動(dòng)閥的不必要的粘滑動(dòng)作。
The EPV-500B 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 action of pneumatic valves.
