Hirata Valves: Mastering Sealing Performance to Unleash Potential

Sealing Performance, Unleashing Potential: Discover Hirata's Valve Mastery

Safety Valves: Installed as safety devices in various pressure vessels and piping lines, these valves prevent internal pressure from rising above a specified value. They are used for gases, air, steam, and liquids, operating quickly when pressure exceeds a given value. Available in various sizes and materials, they cater to a wide range of applications.

Discharge Valves: Also known as flush valves or tank bottom valves, these are often installed at the bottom of tanks. They share a basic seal structure with globe valves and are available in manual and air operation types. They come in ascending, descending, and ram types, in various sizes, pressure ratings, and materials.

Hirata Valve Industry's products are designed and manufactured according to customer specifications, ensuring a wide range of applications across different industries.

In a strategic move to expand its product offerings and market share, Hirata Valve acquired Shida Komusho's safety valve business in 2021.

  • Hirata Valve acquires safety valve business from Shida Komusho

The acquisition allowed Hirata Valve to gain expertise in safety valve design and manufacturing, enhancing the quality and reliability of its safety valves.

Shida Komusho continued to operate its safety valve business post-acquisition, focusing on its core competencies in the industrial gas market. The collaboration between the two companies is expected to benefit both, leading to increased market share and product quality.

Hirata Valve Industry Co., Ltd. offers a diverse range of valve products, each designed to meet specific requirements in various fields. Here's an overview of their product types:

Globe Valves: These valves, known for their spherical body shapes, are excellent for regulating the flow rate of liquids and gases. They are also effective in stopping fluid flow. Hirata Valve offers rubber-lined globe valves suitable for use with seawater. These valves come in various sizes, pressure ratings, and are made from materials like carbon steel, stainless steel, and cast iron. They can be operated manually, by air, or motor.


Gate Valves: Characterized by their straight flow path and minimal pressure loss, gate valves are used to allow fluid to flow vigorously or to stop it completely. Hirata Valve provides rubber-lined gate valves, also used in seawater applications, available in a wide range of sizes and pressure ratings, and made from similar materials as globe valves.

Check Valves: These valves prevent backflow in piping systems and are known for their smooth prevention of backflow without causing excess flow. They maintain stable operating conditions even at low flow rates and are excellent in terms of maintainability and cost reduction. Hirata Valve offers full rubber-lined check valves, suitable for seawater, in various sizes and materials.

Butterfly Valves: These valves are unique for their disc rotation mechanism in the flow path, requiring less space for installation and maintenance. Hirata Valve offers butterfly valves with metal and rubber seats, suitable for small spaces and high-temperature ranges. They come in various sizes, pressure ratings, and materials.

Ball Valves: These valves use a ball with a hole as the valve body, allowing fluid passage when the hole aligns with the pipeline. Hirata Valve provides rubber-lined ball valves, suitable for seawater, and offers them in a range of sizes, pressure ratings, and materials. They are capable of sudden opening and closing and can be made as three-way valves.
