Product details
I. Overview
The X A/B S pneumatic diaphragm single seat angle regulating valve consists of an X A/B type pneumatic diaphragm multi spring actuator and a single seat angle valve. Its structure has the following characteristics:
1. The valve body has smooth flow channels, low resistance, and high flow capacity.
2. It can avoid adhesion, coking, and blockage, and has a certain self-cleaning ability.
3. The valve seat is fixed with threads, with a simple structure and low 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.
