HASS比例阀EPV-500SS技术规格
HASS比例阀EPV-500SS产品介绍
Description
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 actions 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 电子比例阀是一种低成本的计算机控制比例阀，可直接接受 4-20 mA 或 1-5V DC 控制信号。与竞争阀门相比，EPV 性能更好，安装成本更低，运行成本更低。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。
阀门设计具有长寿命的旋转阀杆密封。与气动阀中使用的往复式阀杆密封件相比，旋转密封件更耐用且需要更少的维护。这种密封不会导致气动阀产生不必要的粘滑动作。
EPV 的紧凑尺寸使其更易于操作，并且可以安装在更小的空间内。 EPV 的尺寸约为气动阀的三分之一。
EPV 安装成本低于类似的气动控制阀系统。无需压缩空气、过滤器、调节器、I-P 转换器或气动空气管路。只需将 EPV 连接到控制信号和电源。
EPV 享有五 (5) 年保修。可靠、低维护的设计和重型结构减少了代价高昂的停机时间。
EPV-500SS 由 316 型不锈钢制成。它具有 3/4 英寸管件，端口尺寸为 1/2，Cv 为 3.5。
