i need ans within 8 minutes with draw happy emoji in the end my best wishes ton 31. Apressure reducing valve is the only normally open pressure control valve.a) Trueb) False32. Pressure reducing valves are used to limit maximum system pressure.a) Trueb) False33. Unlike other pressure control valves, the pressure reducing valve senses its pilot from the secondary port of the valve.a) Trueb) False34. When an unlouding valve opens, it directs flow directly back to the tank.a) Trueb) False35. Since the unloading valve is remotely piloted, it can allow flow to return to the tank at minimal pressure.a) Trueb) False36. Flow dictates when an unloading valve will open.a) Trueb) False37. Acounterbalance valve is a normally open flow control valve.a) Trueb) False38. Acounterbalance valve is used to control a cylinder with a negative or overrunning load to move at a controlled rate.a) Trueb) False39. The counterbalance valve should be set at a pressure slightly higher than the load induced pressure caused by the weighton the cylinder.a) Trueb) False40. The brake valve uses a remote pilot to maintain a constant back pressure on the motor.a) Trueb) False41. The brake valve has two pilots for the purpose of allowing the installer more plumbing options.a) Trueb) False42. When the directional control valve is centered, the brake valve allows a controlled amount of back pressure to build inthe line between the motor and the brake valve to achieve dynamic braking.a) Trueb) False43. Aclosed center system maintains constant flow, but no pressure when the directional control valve is centered.a) Trueb) FalseSubject : Hydraulic and pneumatic controlSystem1/044. The type of pump (fixed vs. pressure compensated) designates whether we have an open or closed center system.a) Trueb) False45. In an open center system, flow passes through the valve center and back to tank at low pressure when the valve iscentered.a) Trueb) False47. Flow controls are always adjustable.a) Trueb) False48. Flow controls are often used to control the speed of an actuator.a) Trueb) False49. Flow through a throttling valve will vary if the differential pressure across the valve varies.a) Trueb) False50. Apressure compensated flow control valve maintains a constant flow by maintaining a constant pressure upstream fromthe valve.a) Trueb) False51. Meter-in should only be used with a positive load.a) Trueb) False52. When metering-in one must always use a pressure compensated flow control.a) Trueb) False53. Meter-in refers to controlling the flow going to the actuator.a) Trueb) False
