Ball Valve
Featuring a V-port ball design for precise flow regulation and low-flow resistance characteristics, the ball valve is widely adopted in fire protection pipelines for rapid shut-off operations. Its full-bore structure ensures minimal pressure drop, while the stainless steel ball and PTFE seals guarantee zero leakage even under high-frequency actuation.
Globe Check Valve
A dual-function valve combining the sealing reliability of a globe valve and the automatic backflow prevention of a check valve. Its compact integrated design eliminates the need for separate installation of two valves, significantly reducing space requirements in critical marine systems such as bilge pumping and cooling water circuits.
Butterfly valve
Butterfly Valve
The butterfly valve utilizes a disc that rotates 90 degrees to control flow, featuring a lightweight design for rapid operation, and is ideal for regulating seawater and fuel transfer in low-pressure differential systems. Its compact structure and low-torque actuation ensure efficient performance in space-constrained marine environments.
