Pressure reducer

A pressure reducer assembly comprising

• a connection fitting for connecting said pressure reducer assembly to a pipe or any other water containing element, said connection fitting having a housing with an opening, an inlet exposed to an inlet pressure and an outlet exposed to an outlet pressure provided at said housing and a separating wall inside said housing for separating said inlet from said outlet, said separating wall having an opening;
• a pressure reducer valve and a spring exerting a pressure on said pressure reducer valve in such a way that the pressure reducer valve is controlled by said pressure of said spring for adjusting said outlet pressure downstream of said pressure reducer valve, and
• a pressure reducer insert with an pressure effective cross section inserted into said connection fitting, said insert extending on one side to said opening in said separating wall and being sealed against said separating wall and extending through said opening in said housing and being sealed against said housing,
• and wherein
• said pressure reducer insert is designed in such a way that said pressure effective cross section of said pressure reducer insert in said opening of said housing which is exposed to said inlet pressure is essentially the same as said pressure effective cross section of said pressure reducer insert in said opening in said separating wall exposed to said inlet pressure, and
• said pressure reducer insert is made of plastic material.
