Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of valve free filters, it is recommended to prioritize confirming key technical parameters such as filtration flow rate and filter layer thickness to ensure compatibility with existing water treatment systems.
  • Valveless filter is suitable for industrial circulating water pretreatment or small-scale sewage treatment scenarios. When purchasing, gravity or pressure structure design can be selected based on the treatment scale.
  • When selecting suppliers, reference can be made to indicators such as product compatibility, business qualifications, enterprise activity, industry performance, and industry data support, and priority should be given to selecting companies with higher technological maturity.
  • In chemical or power industry applications, attention should be paid to the selection of corrosion-resistant materials for valve free filters, and it is recommended to verify the actual operational case data of suppliers in similar projects.

Knowledge Base

Q

The selection of filter material for a valve free filter is crucial. On the one hand, the mechanical strength of the filter material should be considered. In the long-term filtration process, the filter material needs to withstand the erosion of water flow and friction between filter materials. If the mechanical strength is not enough, the filter material is prone to breakage, which will affect the filtration effect. For example, if the filter material breaks and produces small particles, it may clog the pores of the filter layer and reduce the filtration efficiency. another

Q

Valve free filter (gravity type valve free filter), as an automated water treatment equipment, is widely used in industrial, municipal, and agricultural fields due to its simple structure and stable operation. Using the siphon principle to automatically control the backwash process, without the need for manual operation of valves or external power equipment (such as backwash pumps). Small footprint, suitable for scenes with limited space.
