Characteristics: Take ESV31 three-way electric reversing ball valve as control mechanism, compared with the solenoid valve, it
is high pressure resistance and has a good ability of pollution resistance. Even if it does not act for a long time, it
still would not be scale formation and failure to operate, it requires lower water quality.
 ESV31 three-way reversing ball valve is with manual function, it also has the function of opening and closing the
signal contact output.
 It uses dual channel stainless steel Y-form filter, has the function of online cleaning and replacing the filter. Even
in poor ......more

Characteristics: It is high pressure resistance and has a good ability of pollution resistance. Even if it does not act for a long time, it
still would not be scale formation and failure to operate, it requires lower water quality.
 ESV31 three-way reversing ball valve is with manual function, it also has the function of opening and closing the
signal contact output.
 It can reduce the higher upstream pressure to a stable and lower downstream pressure.
 It is not affected by the upstream pressure and the flow change.
 It reduced dynamic pressure and static pressure.
 I ......more

Characteristics: The control loop uses stainless steel pipeline connection, which can bear high
pressure and impact, and would not cause intense pressure fluctuations in the
system (even if the closing speed is fast), and will not produce dangerous water
hammer impact in the downstream of the valve.
 Both effectively protect the system from water hammer impacting, and prevent
the regorge impacting the pump frame and the pump bladed. When the system
is restarted, it makes the system slowly pressurized to further prevent the
pressure fluctuations.

Characteristics: Multifunction check valve is usually installed at the pump outlet, with hydraulic
automatic control, slowly open when starting the pump; when stopping the pump,
first fast closing and then slowly closing.
 The multifunction check valve also have functions that water hammer eliminator
on pump outlet, cut-off valve and check valve has.
  The multifunction check valve can realize the valve closing and pump starting function.
 The main valve body uses Y-form dual-chamber diaphragm structure, the seal is soft seal, which has good effect
and ensure the valve zero leaka ......more
