Product details
I. Overview
The XAV pneumatic Venturi angle regulating valve consists of a pneumatic thin film multi spring actuator and a Venturi angle valve. Its structure has the following characteristics:
1. The valve body flow channel is unobstructed, with low resistance, which can avoid adhesion, coking, and blockage, and has a certain self-cleaning ability.
2. Each caliber has three rated flow coefficients, making it easy to choose.
3. The valve seat is fixed with threads, which has a simple structure and small leakage.
The pneumatic thin film multi spring actuator used has a large output force and a compact product structure, making it widely used in situations where pipelines are arranged at right angles. It is suitable for controlling media containing suspended solids, granular substances, or high viscosity.
