A marine gate valve is a linear motion valve designed to start or stop the flow of fluid in shipboard piping systems. It operates by raising or lowering a wedge-shaped gate between two seating surfaces, providing a tight seal when closed. Gate valves are typically used in applications where a full, unobstructed flow is required, but they are not ideal for throttling since partial opening can cause vibration and wear. In marine environments, they are built to withstand seawater corrosion, high pressure, and comply with Navy and MIL-SPEC standards for reliability and safety.

Socket weld pipe connections are used in high temperature and high-pressure environments. Socket weld pipe connections feature a smooth internal bore sized to match the outer diameter of the pipe. The pipe end is inserted into the socket and then fillet welded around the joint, forming a strong, leak-tight seal. Socket weld connections are popular in smaller sized fittings and are permanent.

Chromoly F11 is a forged chromium-molybdenum alloy steel. Unlike its pipe-grade counterpart (P11), F11 is produced for forged components such as flanges, fittings, and valve bodies. Chromoly F11 is used in high-temperature and high-pressure service.
