Pneumatic Angle Control Valve
The angle control valve adopts the top guide structure to realize the adjustment to pressure, flow, temperature and liquid level. It is small size, light weight, low leakage, simple flow route, and low resistance, it can serve liquid fluid with high pressure difference / high viscosity / suspended particles. It is convenient to do self-cleaning and water cleaning. The angle control valve is generally used in condition of bottom-in & side-out.
