Question: A pressure-reducing valve is set to limit the force exerted by a clamping cylinder. The 1.5-in. bore cylinder must not exert more than 2900 lbf to prevent damage to the part being held. At the moment the DCV is shifted to close the clamp cylinder, the supply pressure is 2750 psi.

a. What pressure drop must the pressure reducing valve maintain?

b. If the flow to the clamp cylinder is 8 GPM, what orifice coefficient (k) must be developed by the pressure reducing valve?
