The P41X Stainless Steel Single-Port Exhaust Valve is a commonly used automatic exhaust device in industrial piping systems. It is primarily applied in scenarios such as pump outlets and distribution pipelines, achieving automatic exhaust and air-supply functions through a buoyant ball that rises and falls with water levels. Below are its core details:

Structure and Material

The valve body is made of stainless steel material (such as 304 stainless steel ball float), with a nitrile rubber seal ring. The valve body can be available in gray cast iron or ductile iron (such as HT200 or HQ450), and internally includes stainless steel ball floats, valve rods, and other core components.

Functions and Principles

‌Automatic Exhaust: As the pipe fills with water, the float rises to seal the exhaust outlet, preventing water leakage; when gas accumulates, the water level drops to allow the float to open the exhaust channel, quickly expelling air.‌

‌Vacuum Protection: Automatically draws in air when the pump stops to prevent pipeline破裂 due to vacuum pressure.‌

High Exhaust Flow: The exhaust capacity is several times that of a standard double-hole valve, with the DN200 product's large exhaust flow reaching 2.8 times that of its double-hole valve counterparts.

Technical Specifications

‌Pressure Range: Nominal pressure 1.0-1.6 MPa, with a valve body strength test pressure up to 1.5 MPa.

‌Connection Types: Available in flange or threaded connections, with pipe diameters ranging from DN15 to DN300mm.‌

‌Applicable Medium: Tap water at room temperature, temperature range 0-100°C.‌

Application Scenario

Broadly used in pump outlets, long-distance water conveyance pipelines (with a group set every 500-800 meters) and waterworks facilities that require rapid exhaust pipe systems.
