Control valve, description about Delayed closed Non Return Valve 300X on China Suppliers Mobile

Product Description

The reducing And Stabilizing Control Valve 200X valve consists of main valve, guide valve, needle valve, ball valve and pressure gauge.The pressure reducing valve mainly controls the fixed outlet pressure of the main valve, the outlet pressure of the main valve does not change due to the change of the inlet pressure, and does not change its outlet pressure due to the change of the outlet flow of the main valve.Applicable to industrial water supply, fire water supply and domestic water pipe system.

300X Delayed closed Non Return Valve working principle

1. When the valve feeds water from the inlet, the water enters the main valve control room through the miniature filter, needle valve and one-way valve, and then drains to the downstream through the ball valve.Because the opening of the needle valve is less than the opening of the ball valve, that is, the drainage speed of the control room of the main valve is greater than the inlet speed, so the pressure of the control room decreases, and the inlet pressure acting on the lower end of the main valve disc opens the main valve to supply water to the downstream.

2. When the pipeline stops water supply, if the downstream water begins to flow back, part of the backflow water enters the main control room through the ball valve. Due to the one-way valve, the backflow water cannot flow out of the main control room, causing the main control room to gradually increase pressure and slowly close the main valve.

Production process

Product packaging

We usually use plastic bags and cartons to packing the valve .

Cartons usually are located on pallets
We also pack the valve by plywood cases
