China Stainless Steel Seal Non Rising Stem Gate Valve Manufacturer, Exporters

Stainless steel sealing provides excellent resistance to corrosion of medium, ensuring durability of the gate valve, are commonly used in various industries, including Oil and gas, Petrochemical, Chemical processing, Water and wastewater treatment, Marine and Power generation.

Product Description

GGG50 ductile iron body: is one of the most commonly used materials, which is known for its high strength and toughness.

Stainless steel seat: excellent corrosion resistance makes it suitable for use in a variety of environments, including corrosive environments such as chemical processing plants, offshore installations and water treatment facilities.

Stainless steel seals provide a tight seal, including a gas seal, which minimizes the risk of leakage.

Compared with rising stem gate valves, non-rising stem gate valves occupy a smaller area and are suitable for environments with limited space.

Frequently Asked Questions
What are the advantages of using GGG50 ductile iron for the valve body?

GGG50 ductile iron provides significantly higher tensile strength, ductility, and impact resistance compared to standard gray cast iron, preventing structural damage under mechanical pressure and operational stresses.

When should a non-rising stem gate valve design be selected?

Non-rising stem gate valves are ideal for installations with limited vertical clearance, such as underground pipelines, tight mechanical rooms, and offshore platforms, as the stem threads remain internally contained.

How does the stainless steel seat enhance performance in harsh conditions?

The stainless steel seat provides superior resistance to corrosion, erosion, and chemical degradation, making it suitable for aggressive environments such as water treatment facilities and chemical processing plants.

What types of actuators can be mounted to this valve?

Thanks to the standard ISO 5211 top mounting flange, the valve supports manual gearboxes, electric actuators, and pneumatic actuators for automated process integration.

What connection standards are compatible with this valve?

The valve conforms to extensive international flange standards including BS 4504, DIN 2501, ISO 7005, JIS 5K/10K/16K, ASME B16.1 (125LB/150LB), and AS 2129 Table D and E.

What is the operating temperature range supported by this valve series?

This valve configuration is designed to perform safely and dependably across an operating temperature range of -20°C to 425°C.
