Default Re: How to make hydraulic valve?

JW : steel or iron next to brass would be the best choice for your manifold . Aluminum does not wear well .


Madda : O-rings work well for the seals as you should only have to seal the shaft of the rotor and the rotor cap . between the rotor and the valve block , you should have a lapped fit .
