HASS比例阀EPV-500B产品介绍
EPV-500B 电子比例阀是一种低成本、计算机控制的比例阀，可直接接受 4-20 mA 或 1-5V 直流控制信号。 与竞争阀门相比，EPV 性能更好，安装成本和操作成本更低。 它是精确控制液体和气体流量的理想选择。
EPV 没有反冲和滞后。 这大大简化了控制程序。 阀门通过零背隙螺杆机构打开和关闭。 步进电机直接连接到阀门，无需齿轮。 阀门也可以手动操作。
自适应数字噪声滤波器消除了由于噪声控制信号引起的阀门抖动。 该数字滤波器可以通过电路板上的开关禁用。
阀门设计采用长寿命旋转阀杆密封。 与气动阀中使用的往复式阀杆密封相比，旋转密封更耐用且需要更少的维护。 这种密封不会引起气动阀的不必要的粘滑动作。
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.
