Q747F-16C DN400 cast steel flange hydraulic fixed ball valve, which is suitable for use as opening and closing devices on gathering and transportation pipelines for water, oil, natural gas, drilling fluid and other media. Hydraulic ball valve consists of two parts: hydraulic device and ball valve. The moving device rotates the valve stem and drives the ball to rotate to achieve the purpose of opening and closing. Main features: 1. The ball and valve body of the ball valve are made of high-quality stainless steel and have good anti-corrosion performance. 2. The ball valve adopts metal seal, which can meet the drilling mud medium environment. 3. The hydraulic drive part has a small structural size and can meet the narrow installation environment. 4. The hydraulic drive torque is large, and the hydraulic control panel of the blowout preventer can meet the usage requirements.
2: Features of Q6747Y gas-liquid linkage hard-sealed flange forged steel ball valve:
The standard valve seat adopts a spring structure, which pushes the valve seat towards the ball, ensuring good inlet and outlet two-way sealing performance; using the built-in discharge valve, the middle cavity of the valve body can be discharged outward; the pivot adopts an anti-blowout protection structure. Effectively prevent leakage; low friction coefficient bearings reduce torque to a minimum and facilitate valve opening and closing;
The valve stem is in perfect contact with the valve body, making the anti-static grounding device superior in performance.
It has the advantages of excellent performance, high reliability, wide range of uses and reasonable price.
3. Overview of Q747F-16C DN400 cast steel flange hydraulic fixed ball valve supplied :
The valve body is divided into three parts along the cross-section perpendicular to the axis of the valve channel at the two valve seats. The entire valve is symmetrical along the central axis of the valve stem. High-pressure forged steel ball valves are mainly used on pipelines to cut, distribute and change the flow of media. direction. Its large pivot structure ensures accurate ball center position under high pressure, ensuring the valve's good operating performance.

8: When purchasing our products, please install them according to the following instructions:
a: Remove the protective covers on both sides of the flange end and rinse and clean with the valve fully open.
b: Before installation, the whole machine should be tested according to the specified signal (electric or pneumatic) (to prevent vibration caused by transportation from affecting the performance). Only after it is qualified can it be installed online (wiring should be according to the electric actuator circuit diagram).
C: Before preparing to connect to the pipeline, the remaining impurities in the pipeline must be flushed and removed (these substances may damage the valve seat and ball).
d: During installation, please do not use the actuator part of the valve as a lifting point to avoid damage to the actuator and accessories.
e: This type of valve should be installed in the horizontal or vertical direction of the pipeline.
f: Pipes near the installation point must not sag or bear external force. Pipe brackets or supports can be used to eliminate pipeline deviation.
g: After connecting to the pipeline, please cross-lock the flange connecting bolts with the specified torque.
