Poppet Block Controls The poppet block is the heart of most Shafer Valve Operating Oil flow capacities for the Shafer Poppet Control are: Systems. This double three-way control valve is designed to provide selective directional operation of Shafer Valve operators. Flow @ Flow @ The poppet block control may direct power gas to a set of gas 1000 PSI 2000 PSI hydraulic tanks generating hydraulic pressure for powering the Size (50 F.P.S.) (70 F.P.S.) Test/Rate operator, or it may direct central hydraulic system pressure directly into the operator. The poppet control is designed to handle 1/4 17 G.P.S. 24 G.P.S. 4500/3000 PSI working pressures to 3000 psi. Manual operation may be provided 1/2” 35 G.P.M. - - - 2160/1440 PSI with a removable and lockable handle. (Abbreviations used : F.P.S. - Feet Per Second, G.P.M. - Gallons Per Minute, PSI - Pounds Per Square Inch) In automatic or remote control versions, the control is actuated by pressurizing a piston located directly over the poppets. This is Special Shafer Poppet Controls are available with high done by using a variety of valving as described in the following pressure/high flow characteristics as follows: pages.
