HASS比例閥EPV-500B產品介紹
EPV-500B 電子比例閥是一種低成本、計算機控制的比例閥，可直接接受 4-20 mA 或 1-5V 直流控制信號。 與競爭閥門相比，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 沒有反沖和滯后。 這大大簡化了控制程序。 閥門通過零背隙螺桿機構打開和關閉。 步進電機直接連接到閥門，無需齒輪。 閥門也可以手動操作。
自適應數字噪聲濾波器消除了由于噪聲控制信號引起的閥門抖動。 該數字濾波器可以通過電路板上的開關禁用。
閥門設計采用長壽命旋轉閥桿密封。 與氣動閥中使用的往復式閥桿密封相比，旋轉密封更耐用且需要更少的維護。 這種密封不會引起氣動閥的不必要的粘滑動作。
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.
