High Pressure Forged Ball Valve

High-pressure forged ball valve is a type of ball valve manufactured by forging process, through high temperature and high pressure forging moulding to enhance the denseness and strength of the material, it is suitable for the opening and closing of high-pressure pipeline systems such as oil, natural gas, flow regulation and media isolation.

Structure composition

• Valve body and bonnet:

Forged steel material (such as ASTM A105, F316), three-body split structure design, easy to disassemble and maintain.
Fireproof structure design, extreme high temperature can still maintain sealing performance.

• Ball and seat:

The surface of the ball is mirror polished, full bore design (flow resistance close to straight pipe), made of stainless steel or hard alloy coating.
The valve seat adopts metal hard seal (nickel-based alloy) or soft seal (PTFE), adapting to high pressure, high temperature or corrosive media.

• Valve stem and actuator:

Lower mounted anti-disengagement valve stem, inverted seal structure to prevent media leakage.
Support manual worm gear, pneumatic, electric or liquid linkage operation.

Nominal diameter (DN)

• Standard range: DN15 ~ DN200 (some models support DN50 ~ DN1200 large diameter)
• Common specifications: 1/4 inch ~ 2 inches (corresponding to DN6 ~ DN50)

pressure level

Nominal pressure (PN):

• Conventional models: PN10.0 ~ PN32.0MPa (some up to 42MPa)
• American Standard Grade: ANSI 600, 900, 1500 lbs.
• Working pressure: the highest support 207bar (about 21MPa)

connection method

• Threaded connection: NPT, BSPT, DIN and other standard threads
• Flange connection: standard flange or enlarged flange (when fully jacketed design)
• Welding / ferrule connection: for small-diameter high-pressure scenarios (such as DN15 ~ DN50)

Applicable temperature and medium

Temperature range: -29 ℃ ~ 550 ℃ (conventional models for -20 ℃ ~ 232 ℃)
Applicable medium:

• General type: water, steam, oil, natural gas
• Special type: slurry containing solid particles, corrosive gases/liquids (need to match the stainless steel or carbide material)

Structure and design parameters

• Valve body material:

Carbon steel (ASTM A105), stainless steel (304/316), forged steel

• Seal form:

Soft seal: reinforced polytetrafluoroethylene (PTFE / PEEK), temperature ≤ 232 ° C
Metal seal: nickel-based alloy or hard coating, high temperature / high pressure resistance

• Driving method:

Manual (worm gear/handle), pneumatic, electric

shape and installation characteristics

• Flow path design: full through diameter (flow resistance close to straight pipe) or reduced (for small flow control)
• Structure length: according to the different diameter, the range of 90mm ~ 530mm (such as DN15 corresponds to 90mm, DN200 corresponds to 530mm)
• Fireproof design: valve stem anti-detachment structure, metal seal fireproof redundancy.

Features and Benefits

• High Strength & Reliability:

Forging process enhances the tensile strength and impact resistance of the material, suitable for high-pressure environments above 42MPa.
Fireproof and anti-static design, safe operation under extreme working conditions.

• Excellent sealing performance:

Dual sealing surface structure (metal-to-metal/soft seal), to achieve zero leakage, vacuum system can also be used.
The sealing surface is resistant to erosion and maintains high sealing performance after long-term use.

• Convenience and economy:

Fast opening and closing with 90° rotation, low operating torque and remote control.
The flow resistance is very small, reducing energy consumption; maintenance costs are lower than gate or globe valves.

Applications

• Energy transmission: oil, natural gas long-distance pipeline and city gas system.
• Chemical and electric power: high-pressure steam, acid and alkali media and high-temperature circulating water control.
• Special working conditions: oxygen, hydrogen peroxide, ethylene and other dangerous media pipeline.

• Medium adaptability: the only valve type that can simultaneously meet the high pressure, high temperature, strong corrosion and hazardous media control.
• Long life design: forging material fatigue resistance, sealing structure wear-resistant, reduce the frequency of replacement.
• Safety: fire, explosion and anti-static characteristics in line with high-risk industry safety standards.
