Throttle manifold JG103-35 .

Product Overview The Throttle manifold JG103-35 is a high-end product of Yancheng Kaifa Petroleum Machinery Co., Ltd., engineered as a High-Performance Throttle Manifold and Quality Throttle Manifold for high-pressure oil and gas well pressure control. As a core blowout prevention device, it precisely regulates casing pressure via choke valve adjustment (with blowout preventer closed), maintaining bottom hole pressure marginally above formation pressure to block formation fluid inflow. It also enables soft well shut-in through gradual pressure release and emergency blowout relief to protect wellheads when pressure exceeds 35MPa—critical for safe and compliant operations in high-pressure oil/gas fields worldwide. Technical Specifications Model: JG103-35 Nominal Diameter: 103mm (main manifold body) Rated Working Pressure: 35MPa (designed for high-pressure well operations) Material: High-strength anti-sulfur alloy steel (NACE MR0175 compliant) Choke Valve Type: Manual / Hydraulic / El…
