Emerson introduces high pressure water glycol regulator

The 50-4000 is designed with an integrated bypass valve that transitions from high flow to precision control at a preset pressure. This enables accurate control of high-pressure water glycol for offshore hydraulic power unit applications, while decreasing subsea wellhead control system pressurization time by up to one-third.

The robust design of this product solves many challenges that deepwater customers face, including slow umbilical fill rates, unreliable and inaccurate regulator performance, increasing failure rates, and high maintenance costs. The 50-4000 precisely controls pressure across large flow variations up to 15,000 psig/1034 bar, enabling it to reduce hydraulic power unit high-pressure components, leak paths and maintenance costs while eliminating complex startup procedures.
