H42W Stainless Steel Screw Bottom Valve

Product Introduction

H42X PumpFoot Valve is an energy-saving valve, usually installed at the bottom end of the pump's underwater suction pipe. It prevents liquid in the pump pipe from returning to the water source, functioning as a one-way inlet.

Detailed Introduction

Overview of H42X Pump Foot Valve

H42X Pump Foot Valve is an energy-saving valve, typically installed at the bottom end of the pump's underwater suction pipe. It restricts the return of liquid in the pump pipe to the water source, serving as a one-way inlet. The valve cover has multiple water inlets and reinforcing ribs, making it less prone to clogging. It is mainly used in water suction pipelines, serving as a water channel and support. Available in single-flap, double-flap, and multi-flap types, with flange or threaded connections.

H42X Structural Principle

The H42X consists of components such as the valve body, valve flap, valve cover, bushing, and sealing ring. Water from the source enters the valve body through the valve cover. Under fluid pressure, the valve flap opens to allow water flow. When the pump stops, the pressure in the outlet pipe quickly closes the valve flap, preventing liquid from flowing back to the water source. This ensures smooth water pumping while minimizing water energy loss.

H42X Features

1. The structure of the H42X is ideal in terms of both flow rate and process requirements. Additionally, it does not cause turbulence during drainage.
2. It can be provided with all current standard interfaces, such as welded, clamped, or threaded types.
3. The valve body surface can be mechanically or electropolished according to customer requirements, with a precision of up to 0.25 μm.
4. The H42X can be manual or pneumatic. Each water pump requires the installation of one foot valve. Foot valves are typically installed below the water level, while above-water foot valves are installed above the water level. It is an upgraded version of traditional foot valves, serving as an ideal water priming device and can also replace vacuum pumps and vacuum suction devices.
