A pressure reducing valve is a valve that reduces the inlet pressure to the required outlet pressure by regulation and automatically maintains a stable outlet pressure by relying on the medium itself. 1. Working Principle The pressure reducing valve mainly changes the throttling area to change the flow rate and the kinetic energy of the
Troubleshooting of butterfly valves (I) Seal leakage Cause analysis Damage of seals: This is one of the most common causes of seal leakage. Seals may be damaged due to long-term use, wear, aging, chemical corrosion or high-temperature deformation. For example, in butterfly valves used in high-temperature steam pipelines, soft seals may lose elasticity due to
