JIS 5K 10K Non-Rising Stem Gate Valve

A JIS 5K/10K Non-Rising Stem Gate Valve is a specialized gate valve designed in accordance with Japanese Industrial Standards (JIS), particularly for pressure ratings of 5K (approximately 5 kg/cm²) and 10K (approximately 10 kg/cm²). These valves are widely used in various industrial applications due to their robust construction, reliability, and efficient flow control capabilities.

 Construction and Design

1. Non-Rising Stem Mechanism: The stem of the valve does not move vertically while the valve is operated. Instead, it rotates in place, which makes it ideal for environments with limited vertical space.

2. Gate Mechanism: The valve features a gate or wedge that moves perpendicular to the fluid flow. When the valve is fully open, the gate is retracted entirely, allowing for unobstructed flow. When closed, the gate provides a tight seal.

3. Materials:

   - Body: Typically constructed from durable materials like cast iron, ductile iron, carbon steel, or stainless steel.

   - Gate: Made from corrosion-resistant materials to ensure a tight seal and long-lasting performance.

   - Stem: Usually made of stainless steel for durability and resistance to corrosion.

 Standards and Specifications

- JIS Standards: These valves are designed to meet the Japanese Industrial Standards, ensuring high quality and compatibility with other JIS-compliant equipment.

- Pressure Ratings: Available in 5K and 10K pressure ratings:

  - 5K: Suitable for systems with a pressure rating of up to 5 kg/cm².

  - 10K: Suitable for systems with a pressure rating of up to 10 kg/cm².

- Size Range: Commonly available in sizes ranging from DN50 to DN600, accommodating various pipeline diameters.

 Features

1. Compact Design: The non-rising stem design saves vertical space, making it ideal for underground or confined installations.

2. Clear Flow Path: When fully open, the gate is out of the flow path, ensuring minimal pressure drop and efficient fluid flow.

3. Reliable Sealing: Provides a tight seal, either through metal-to-metal contact or with resilient seating, to prevent leakage when the valve is closed.

4. Operation Options: Can be operated manually using a handwheel or wrench, or automated with electric, pneumatic, or hydraulic actuators.

 Applications

- Water Supply and Distribution: Widely used in municipal water supply systems and industrial water distribution.

- Industrial Piping: Suitable for various industrial applications requiring reliable flow control.

- Sewage and Wastewater Treatment: Used in managing the flow of wastewater and sewage.

- Oil and Gas Industry: Employed in pipelines and processing plants to control the flow of oil, gas, and other hydrocarbons.

- Power Plants: Utilized in power generation facilities for controlling the flow of steam, cooling water, and other fluids.

 Advantages

- Space Efficiency: Ideal for installations with limited vertical space due to its non-rising stem design.

- Durability: Made from high-quality materials to ensure long service life and reliability.

- Maintenance: Simple design allows for easy maintenance and repair, reducing downtime and operational costs.

- Compatibility: Designed to meet JIS standards, ensuring compatibility with other JIS-compliant components and systems.

 Summary

The JIS 5K/10K Non-Rising Stem Gate Valve is a versatile and reliable solution for controlling fluid flow in a variety of industrial applications. Its robust construction, space-efficient design, and adherence to Japanese Industrial Standards make it an excellent choice for water supply systems, industrial piping, sewage treatment, and more.
