The remote control float valve controls the opening and closing of the main valve through the remote float level signal, achieving automatic water inlet and stable liquid level
○ Nominal diameter: DN50-DN600mm
○ Nominal pressure: PN10 – PN25
○ Applicable media: clean water, domestic cold water, fire water
○ Operating temperature: 0 ° C to+120 ° C
○ Connection method: flange connection
○ Valve body material: ductile iron, cast steel, stainless steel
○ Sealing/membrane material: NBR, EPDM, Viton
○ Control method: Pilot operated hydraulic remote control, connected to an external float valve through a conduit
○ Action principle:
Water level drops → floating ball falls → pressure relief of pilot valve → main valve opens for water replenishment
The water level rises to the set height → the float rises → the pilot valve closes → the main valve slowly closes
○ Closing feature: Slow closing design to reduce water hammer
○ Remote control distance: ≤ 20 meters (catheter length, recommended ≤ 10 meters to ensure sensitive response)
○ Adopting remote floating ball control to achieve remote automatic liquid level adjustment
○ The main valve opens and closes smoothly without a water hammer, ensuring the safe operation of the water supply system
○ No need for external power drive, relying on hydraulic automatic control for energy saving and environmental protection
○ Compact structure and reliable sealing, suitable for working conditions with clean water and room temperature media
○ Easy and flexible installation and maintenance, suitable for horizontal or vertical pipeline layout and use
○ Automatic water inlet control for high-level water tank, maintaining stable operation at the set liquid level
○ Municipal water supply tower or reservoir liquid level linkage adjustment inlet valve
○ Pre stable liquid level protection device for variable frequency water supply system in building communities
○ Industrial cooling tower makeup water pipeline achieves unmanned automatic control
○ Fire water pool liquid level monitoring and automatic water replenishment safety control node
The sensing component of the multifunctional water pump control valve is a diaphragm, which has a smaller flow resistance coefficient than diaphragm and piston types.
It can be used as a pressure holding valve or a pressure relief valve. When the set pressure is exceeded, the relief valve becomes a path with low resistance
The micro resistance slow closing check valve adopts a double flap slow closing and streamlined flow channel design, with low resistance and smooth closing
