HYQ type high-performance pressure reducing valve is a product that does not need any external energy and realizes automatic adjustment by using the regulated medium's own energy. The product's biggest feature, can work in the place of no electricity, no gas, and at the same time saves energy, the pressure setting value can be adjusted at will in the operation. The use of fast-opening flow characteristics, sensitive action, good sealing performance, and thus widely used in petroleum, chemical, electric power, metallurgy, food, textile, machinery manufacturing and construction, and other particularly industrial equipment for gas, liquid and steam media pressure reduction, pressure stabilization (for post-valve regulation), or pressure relief, pressure stabilization (for pre-valve regulation) of the automatic control. It opens and then discharges the full amount; when the pressure drops to the specified value, the valve closes automatically to ensure the safe operation of the equipment and pipeline.
