When choosing a valve, the valve can be selected according to the function of the valve to choose the valve needed. ZECO water treatment valves are classified according to type：
Water control valves, divided into pressure reducing valves, pressure relief valves, modulating float valves, etc., which can control the pressure of the pipeline and the water level of the tank.
Balancing valves, divided into pressure independent control valves and static balancing valves, can control the pipeline flow and differential pressure.
Gate valves, divided into metal seal gate valves and resilient seated gate valves, can play the role of shut-off.
Air valves, divided into single orifice air release valves and double orifice air release valves, can release the air in the pipeline.
Butterfly valve, divided into rubber lined butterfly valve and metal butterfly valve, according to the space is smaller than the gate valve, can play the role of shutting off.
In the selection of product materials, according to the working conditions to choose the corresponding valve body material and internal parts material.
For freshwater service, ductile iron and cast iron valve bodies are usually used.
For seawater conditions, aluminium bronze, stainless steel or QT450-NiCr are usually used.
Zeco Static balancing valves allow for easy and accurate adjustment of flow rates, effectively solving the problem of uneven cooling and heating and hydraulic disorders in HVAC systems.
Zeco Air valve can effectively vent a large amount as well as a small amount of air, draining the pipeline in time. When the pipeline needs to be replenished, it can draw in air from the atmosphere in time.
Zeco pressure relief valves are used in conjunction with pressure reducing valves to ensure the normal operation of the pipework. Modulating float valves control the water level at the tank to ensure that the tank does not overflow.
Zeco resilient gate valve has a WRAS approved internal and external epoxy sprayed cover that can resist corrosion and high quality rubber material that can maintain its efficacy in water for a long and stable period of time.
Zeco rubber lined butterfly valve is WRAS approved epoxy sprayed inside and out, with low switching torque and small installation space.
