The valves to be used in sub-marine environments for isolation and controlling can be referred as subsea valve. Subsea valve is characterized by high pressure resistance, large diameter and low torque, mainly used in offshore oil and gas engineering pipeline system and transportation pipeline, or deep-sea submersible sometimes. The valves designed for superb sealing can be up to a depth of 4000 meter and mainly the type of ball valves, gate valve, check valve remotely by hydraulic actuators, ROV and handwheel ( for shallow water).
PERFECT manufacture and provide various valves for harsh subsea environments. That valves can be designed with the actuator configuration required to meet your needs such as trunnion mounted ball valve, subsea floating ball valve, subsea double expanding gate valve, subsea check valve. Our subsea valve is available from ANSI 1500 class up to 2500 pressure and We can also accept the OEM design. Please review the charts below for available sizes & pressure & material or fill the contact form below.
