IND-PTV - Check Valves

The video tutorial explains the function and types of check valves, which allow fluid to flow in one direction. It covers ball, swing, lift, and stop check valves, detailing their mechanisms and applications. The concept of cracking pressure, the minimum pressure needed for valve operation, is also discussed. The tutorial concludes with an invitation for feedback.

What is the primary function of a check valve?

• To increase the pressure of the fluid

• To allow fluid to flow in both directions

• To allow fluid to flow in only one direction

• To control the temperature of the fluid

Which type of check valve uses a spherical ball to block flow?

• Swing check valve

• Lift check valve

• Ball check valve

• Stop check valve

How does a swing check valve control fluid flow?

• By manually adjusting the flow

• By using a spring-loaded ball

• By swinging a disc on a hinge

• By lifting a disc off its seat

What is a unique feature of a stop check valve?

• It can be manually overridden to stop flow

• It operates without any external control

• It uses a spring-loaded mechanism

• It has a spherical ball to block flow

What does the term 'cracking pressure' refer to in check valves?

• The maximum pressure a valve can withstand

• The pressure at which a valve begins to open

• The pressure needed to maintain a valve in the open position

• The pressure required to close a valve
