There is more to control than just process fluids in the subsea system. Rotary disc valves are readily used for both chemical injection and for hydraulic distribution. Chemicals are used in many critical applications to remove blockages, reduce corrosion, improve crude oil quality and of course for flow assurance.
Why rotary disc valves, the operational benefits. In the main, the systems used for chemical injection and hydraulic distribution tend not to have significant fluctuations in pressure. What you do need, however, is a valve that can reliably perform in dirty fluid conditions. The subsea rotary disc (or sometimes referred to as rotary gate) valve is ideal for simple and reliable operation in these conditions delivering either isolation or diverter solutions.
Benefits of BEL Valves Rotary Disc Valves. Simplicity of design is key with the rotary disc valve design. Metal to metal sealing across disc and seat delivers ease of operation, reliability and robust performance even in the dirtiest of applications. The design is reliable down to 4,500m water depth and up to pressures of 16,500 psi. Depending on application the rotary disc can be operated hydraulically with spring return for fail safe application and manual override or via ROV. Both options are compact in design and ideal for use where space is restricted.
