Abstract
A pressure reducing valve applied to products such as a water purifier, a bidet, a boiler, an instant water heater, and so on is provided. The pressure reducing valve has advantages of being capable of increasing productivity and reducing manufacturing cost of products by omitting a diaphragm, a metal poppet valve, and other parts which are essential in the conventional art. In addition, it is possible to prevent leakage of fluid from a peripheral connection part of the pressure reducing valve, and damage of the connection part due to high-pressure operation of the pressure reducing valve, thereby extending the lifespan of products.
