Product Description
1. 3PC Forged Steel Hard Seal Ball Valve adopts three piece split structure. The valve body consists of left, middle and right sections connected by high strength long bolts, featuring high structural strength and reliable sealing for high pressure working conditions.
2. The valve body is made of high quality forged steel with heat treatment and precision machining. It has good mechanical properties and corrosion resistance, suitable for medium and high pressure working conditions.
3. The ball and seat are hardened or overlaid with Stellite alloy, suitable for severe working conditions such as high temperature, high pressure and particle containing media.
4. The seat adopts elastic loading or spring loaded design. It provides preload sealing force during initial assembly, and the sealing effect is further enhanced under medium pressure to ensure reliable sealing at both low and high pressure.
5. The stem is of bottom mounted design with low operating torque for easy opening and closing.
6. The product design complies with ASME B16.34 standard. It is widely used as shut off device for pipelines of water, air, natural gas, oil and other media to realize medium cut off and isolation.
Features & Benefits
1. Forged Steel Construction: The valve body is machined from three pieces of forged steel, free of casting defects, with high structural strength and strong pressure resistance.
2. Sealing Performance: Metal hard seal mating pair resists high temperature high pressure, wear and particle containing media for stable sealing performance.
3. Elastic Seat: The elastic loading structure of seat ensures tight contact of sealing surfaces and reliable sealing even under low pressure.
4. Stem Safety Structure: Bottom mounted anti blowout stem design eliminates stem ejection risk.
5. Fire Safe and Anti Static: Equipped with fire safe and anti static structure, suitable for flammable and explosive media.
6. Accurate Handle Indication: Flat stem structure enables handle position to accurately reflect valve open and close status.
7. Locking Mechanism: Limit stops are provided at fully open and fully closed positions to prevent misoperation.
8. Easy Operation: Precision fit between ball and stem reduces friction and operating torque for effortless handle operation.
