Product Details
The hydraulic throttle manifold can remotely control the opening and closing of the hydraulic throttle valve, with the standpipe pressure, casing pressure, and hydraulic throttle valve opening/closing position displayed on the control panel. This product, an essential indispensable device for successfully controlling well surges, blowouts, and implementing oil and gas well pressure, is mainly used to maintain the balance of bottomhole pressure.
The well testing throttling manifold is set between the high-pressure upstream equipment and the low-pressure downstream equipment to generate the pressure drop required by the separation equipment. By changing the opening of the throttle valve with the blowout preventer closed, the manifold can maintain a slightly higher casing pressure than the formation pressure to prevent formation fluids from flowing into the well, thereby avoiding oil pollution.
The throttling manifold consists of throttling valve, gate valve, pipeline, fittings, and pressure gauge. When the pressure inside the well increases, the opening of the throttle valve (manual, hydraulic, or fixed type) is adjusted to discharge the fluid inside the well to reduce the well pressure. If the pressure is too high, the gate valve should be opened to blow out the fluid from the well.

1. Technical Breakthroughs & Market Gaps Filled
Domestic First-Innovation Design. Technical performance indicators are continuously optimized, machining precision reaches international standards, and the domestic gap in hydraulic control technology for throttle manifold systems is filled.
Certified under API 16C "Specification for Choke and Kill Systems", fully compatible with North American and European market entry requirements.
2. Extreme Environmental Adaptability
Wide Temperature Range Working (-20°C to +70°C), hydraulic oil can be selected anti-wear type or aviation hydraulic oil, adapt to corrosive oil and gas environments, to ensure stability in the desert, polar and other complex working conditions.
The hydraulic system integrates accumulator groups, enabling one complete "open/close" valve operation during power outages to enhance emergency response capability.
3. Intelligent Monitoring & Remote Control
Equipped with pressure transmitters, valve position transmitters, and digital display instruments for precise monitoring of system pressure, riser pressure, casing pressure, and valve position (accuracy ±0.5% FS).
Support remote control of hydraulic throttle valve opening and closing, through the three-position four-way directional valve to achieve rapid response, improve well control safety. The control distance can reach 30-50 meters.
4. Customizable Control Configuration
The number of controlled objects can be customized, with our solution successfully implementing choke manifold control panel capable of simultaneously controlling up to 28 hydraulic valves
5. Market Recognition & High Customer Repeat Purchases
Products exported to over 20 countries including the Middle East, Europe, Latin America and Russia, with long-term service for CNPC, Sinopec, and other major enterprises, demonstrating high customer repurchase rates.
6. Industry Benchmark Enterprise
Certified as China National Petroleum Corporation (CNPC) Class-A equipment supplier, holding official recognitions including "Safety Production Standardization Enterprise" and "Well Control Equipment Class B Manufacturer".
7. The throttle valve can be opened and closed within 20 seconds under product test conditions.
8. A mid-position non-leakage type three-position four-way manual directional control valve can be adopted, which has a small operating torque and ensures the accuracy of the throttle valve position switching and the stability of the throttle valve switch position.
9. The control box control pressure can be configured according to the rated working pressure required for driving the throttle valve, meeting various working requirements.
10. A backup air source can be added. In case of on-site air supply interruption, it can supply the valve position sensor and valve position indicator to work usually, providing data for emergency manual operation.
11. An insulation system can be added to heat the hydraulic oil in the oil tank and the pneumatic pipeline, ensuring the viscosity of the oil in cold regions and avoiding ice blockage of the pneumatic directional control valve due to water vapor in the air source.
12. The standpipe pressure and casing pressure data are collected by hydraulic sensors, which have fast response speed, high accuracy, good stability and mature technology, and have natural explosion-proof features. Moreover, they can work without power (independent of air source and power supply).
13. Data is displayed on a 360° pointer-type large dial, which is intuitive and has a maximum resolution of 20 PSI.
14. The pneumatic hydraulic pump has mature technology, low start-up frequency, is safe and reliable, and has low energy consumption.
