• Maniks Stop Check Valve Introduction
• Stop check valve plays a vital role in many
  industries to protect boilers and related

• Theory
• These valves are an altered rendition of the
  standard globe stop valve, which has the valve
  stem forever joined to the globe plate. In the
  stop check arrangement, the stem head skims in
  the globe circle. At the end of the day, they are
  by and large utilized as a globe valve to begin
  or stop the stream of the media, yet they
  additionally go about as a check valve to
  consequently close should weight be lost, in this
  manner averting reverse that could make harm
  hardware, for example, boilers or pumps.
• The inside circle, which isn't connected to the
  stem, executes as a lift check enabling it to
  unreservedly climb and down when the stem is
  raised to alter the opening and shutting. If
  necessary, the stem can be physically brought for
  stream down to be halted or totally stopped.

• Actual USE OF STOP CHECK VALVES
• These stop check valve are for the most part
  utilized as a part of energy plants, in
  applications, for example, heater course, steam
  age and kettle encourage water, turbine cooling,
  and starter water and wellbeing frameworks. They
  likewise are utilized as a part of different
  applications where channeling fashioners need to
  consolidate the properties of a globe and check
  valve. Such applications may incorporate
  high-temperature benefit, warm recuperation
  steam, high-weight security benefit, geothermal
  administration, utilities, oil generation and
  refining, wellbeing frameworks, shutdown cooling,
  and hydrocarbon preparing.
