Remote cut-off valve

An air gun array, comprising:

• (a) a plurality of air guns placed in a spaced relationship;
• (b) a single fluid supply line for supplying a fluid to the air guns;
• (c) a hose bundle coupled to the fluid supply line, said hose bundle carrying a compressed fluid therethrough and an electrical conductor for carrying address signals and power;
• (d) a remotely operated valve placed near the array and connected between the hose bundle and each said air gun for supplying a compressed fluid from the hose bundle to the air guns, each said valve further comprising:
• (i) a body having a bore therethrough;
• (ii) an input port formed in the body, said input port coupled to the fluid supply line for receiving the fluid therefrom;
• (iii) an output port formed in the body, said output port having a sealable recess terminating in the bore, said output port also coupled to an associated air gun for supplying the fluid to that air gun, said input and output ports being in fluid communication with each other and with the bore;
• (iv) a poppet paced in the bore, said poppet adapted to move in the bore between an open and a close position, said poppet having a free end adapted to seal the output port recess when the free end is placed in the output port recess, the close position being defined when the poppet seals the recess;
• (v) a motor coupled to said poppet for moving the poppet between the open and close positions;
• and
• (vi) a one way relief valve having a preset threshold pressure coupled between the bore and the output port, said relief valve opening to provide fluid communication between the bore and the output port when the pressure in the output port exceeds the pressure in the bore by the threshold amount;
• and
• (vii) a decoder coupled to said motor and the conductor, said decoder adapted to receive addresses for the air guns and power and in response thereto causing the motor to turn so as to move the poppet between the open and close positions.
