结构特点和用途Structural Feaures and Application

本系列调节阀由阀门和HA-系列薄膜气动执行机构组成。采用平衡式阀瓣和双座套筒宽导向结构，有效消除机械振动噪声并提高使用寿命。采用低流阻、高容量阀体和套筒，具有流量大、调节范围大以及很小的密封泄露（见性能指标）。执行机构接受0.14，,028,0.4MPa的起源动力，控制调节阀开度，实现对管路内介质的压力、流量、液位等受控参数的控制。

本产品适用于低流阻、大容量和有中等密封要求（ANSI B16.104 Ⅲ级）的工况条件。广泛应用于化工、轻纺、冶金、火电等行业的自动控制系统中。

This series valve by valve and HA - film series pneumatic actuators. With balanced disc and the two-seater sleeve width guide structure, effectively eliminate the mechanical vibration noise and improve the service life. Body and sleeve with low flow resistance, high capacity, large flow, the adjusting range is large and small seal leak (see performance index). Enforcement agencies to accept, 0.14, 028,0.4 MPa the origin of the power, control the valve opening, implementation of piping within the medium pressure, flow, liquid level control of the controlled parameters, such as.

This product is suitable for low flow resistance, large capacity, and have a secondary containment requirements (ANSI B16.104 Ⅲ) conditions. Are widely used in chemical industry, textile, metallurgical, coal and other automatic control system.
