Product Characteristics

The sealing surface of stainless steel valves is welded with Stellite or cobalt chromium tungsten alloy, with a hardness of ≥ HRC58, a temperature resistance of up to 600 ℃, and a leakage level of ANSI Class IV. It is suitable for high-temperature and high-pressure corrosive media such as high-temperature dilute nitric acid.

Stainless Steel Valve Characteristics

Core Advantages

1. Wide Temperature Range & Stable Working Ability

Conventional stainless steel gate valves can operate stably within the range of -200 ℃ to 600 ℃. They are not easily oxidized or deformed at high temperatures and have no risk of brittle fracture at low temperatures, making them suitable for extreme working conditions.

2. High Sealing Reliability & Low Maintenance Cost

Metal hard seal type: Welded with hard alloy (Stellite), offering service lives 3–5 times that of carbon steel valves with ANSI Class IV leakage levels.

Soft seal type: Uses PTFE/PFA materials to achieve ANSI Class VI zero leakage. The anti-rust nature of stainless steel prevents valve stem jamming.

Valve Advantages

Packing & Delivery

Frequently Asked Questions

QWhat is the operating temperature range of these valves?
They can operate stably within -200 ℃ to 600 ℃. The standard product specification generally covers -30 ℃ to 425 ℃, offering broader adaptability than carbon steel.
QWhat sealing grades are available?
We offer metal hard seal (ANSI Class IV leakage) with Stellite alloy surfaces, and soft seal (ANSI Class VI zero leakage) using PTFE/PFA fluorine materials.
QWhich international standards do the valves comply with?
The valves comply with multiple internationally recognized standards including EN, API, DIN, and GOST.
QWhat industries are these valves best suited for?
They are ideal for chemical processing, food and pharmaceuticals, oil and gas, power generation, and municipal water treatment.
QHow long is the service life compared to carbon steel?
Stainless steel gate valves with hard alloy sealing surfaces typically have a service life 3–5 times longer than conventional carbon steel valves.
QWhat is the hardness of the sealing surface?
The sealing surface is welded with Stellite or cobalt chromium tungsten alloy, achieving a high hardness of ≥ HRC58.
