Oct 06, · It is the distance the lifter will move. It is also called "lobe lift." Some camshaft manufacturers list this value. How is it measured? Lift can be measured using a Dial Indicator. You will need to know the Rocker Arm Ratio to calculate. On most engines, valve lift will be greater than the lobe lift. The formulas are as follows Valve Lift = Lobe Lift x Rocker Arm Ratio. Lobe Lift = Valve Lift / Rocker Arm Ratio

Types of Check Valves Their Recommended Applications

Types of Check Valves Ball Check Valves Unlike other valves, ball check valves use a spherical ball inside their bodies to help control the flow direction in pipes and systems. This ball rotates freely when fluid passes through the system, which causes a wiping motion and even wear between the ball and seat.

Check Valve an overview ScienceDirect Topics

Aug 02, 2010· There are two types of lift check valves horizontal and vertical. Both of these valves use either a disk or ball and the force of gravity to close the valve in the event of reverse flow. The horizontal lift check valve has a seat that lies parallel to the flow. The result is an Sshaped body style that mandates the valve be installed in the horizontal position only and has a flow that enters from below the seat.

A ball check valve is a check valve in which the closing member, the movable part to block the flow, is a ball. In some ball check valves, the ball is springloaded to help keep it shut. For those designs without a spring, reverse flow is required to move the ball toward the seat and create a seal. The interior surface of the main seats of ball check valves are more or less conicallytapered to guide the ball into the seat and fo
