Product description
Subsea ROV gate valve employ GBS profile slab gate valve, and ROV mechanical actuator, usually used for Marine oil and gas transmission and exploitation, such as Subsea Manifold (PLEM) / Subsea Pipeline End Termination (PLET) / Subsea Transport Pipeline / Other subsea Produce system. It has the characteristics of corrosion resistance, high reliability and maintenance and can operate in the underwater environment for a long time.
Design Features：
01. Metal-to-metal Seats Subsea valves generally use metal to metal seats,with the surface hardened.
02. Prolonged life soft seals Compared to O-rings, Lip-seal of PTFE enjoyssuperior chemical and ageing resistance, insusceptible to explosivedecompression in gas service.
03. Metal ring joints Metal ring joint, as primary seals of flanges,can seal against internal service fluid pressure and external pressure fromocean.
04. Multi-seal stem sealing solution Stem packing is the most vulnerable area as it isstructured in dynamic sealing.
05. The linear type driving device The driving device can meet the requirements of any water depth through the design of pressure balancer.
06. ISO 13628-8 ROV interface Valves are provided with standard ROV interfaceas per ISO 13628-8.
07. Cathodic protection The design all metallic components ensure theelectrical continuity; every valve, actuator and other connection devices canbe linked to cathodic protection system.
