Valve system and methods thereof

A valve system comprises:

• (a) a valve comprising
• i. a valve body having an opening and an interior,
• ii. wherein the valve may be operated to a closed or to an open position;
• (b) a davit system comprising:
• i. a first pillar having an upper end and a lower end, wherein the lower end of the first pillar is attached to an upper surface of the valve body;
• ii. a second pillar having an upper end and a lower end, wherein the lower end of the second pillar is attached to an upper surface of the valve body;
• iii. a pivot arm having a first end and a second end, wherein the first end of the pivot arm is rotationally attached to the upper end of the first pillar, wherein the second end of the pivot arm is removably attached to the upper end of the second pillar and wherein the pivot arm straddles the valve body opening when the second end of the pivot arm touches the upper end of the second pillar;
• and
• (c) a closure cap system comprising:
• i. a closure cap adapted to seal the valve body opening, wherein a means for sealing the closure cap is disposed between the closure cap and the valve body when the closure cap is in a closed position;
• and
• ii. a cap stem having an upper end and a lower end, wherein the lower end of the cap stem is attached to the closure cap and the upper end of the cap stem is disposed through a central portion of the pivot arm;
• and
• iii. wherein a means for lifting and lowering the closure cap engages the cap stem to lift or lower the closure cap.
