View SpecificationBuyers This Category Suits
- Water and wastewater treatment plant operators needing reliable isolation valves for process lines
- Power plant engineers specifying valves for auxiliary systems and boiler feedwater circuits
- Petrochemical and chemical plant procurement teams requiring valves that meet DIN or BS standards
- Marine and offshore contractors sourcing valves for shipboard piping systems
- Pharmaceutical and metallurgical facilities needing valves with metal seats for clean and aggressive media
What It Fixes on the Line
- Non-rising stem valves are needed where vertical space is limited and the stem cannot extend above the valve body
- Rising stem valves are required in applications where visual confirmation of open or closed position is critical
- Valves with metal seats are needed for high-temperature or high-pressure services where elastomeric seats degrade
- Mixed standards across projects require valves that conform to DIN, BS, or other international specifications
- Buyers need a single source for both non-rising and rising stem metal seated gate valves across a wide range of nominal diameters
Why Engineers Specify This Family
Advantage
Non-rising stem design reduces vertical space requirements, suitable for installations with limited overhead clearance
Advantage
Rising stem design provides visual indication of valve position, critical for safety and operational checks
Advantage
Metal seats offer durability and performance in high-temperature and high-pressure environments where rubber seats fail
Advantage
Compliance with DIN3202 and BS5163 standards ensures compatibility with international piping systems
Advantage
Nominal diameter range from DN10 to DN2600 covers small service lines through to large industrial headers
Advantage
All valves are produced in the same Tianjin facility under ISO 9001 and ISO 14001 quality and environmental systems
Where These Valves Are Installed
- Isolating feedwater lines in low-pressure boiler systems within power generation plants
- Controlling flow in raw water and treated water pipelines in municipal water treatment facilities
- Shutting down process lines in chemical engineering plants handling corrosive or high-temperature fluids
- Managing flow in heating circuits of district heating networks operating at medium pressure
- Securing pipeline isolation in pharmaceutical production areas where clean and reliable sealing is essential
Industries and Guides for This Family
Metallurgy

Metal Seated Gate Valves FAQ
What is the difference between non-rising stem and rising stem metal seated gate valves?
Non-rising stem valves have the stem fixed to the disc; the stem does not move up or down during operation. Rising stem valves have a stem that moves upward when opened, allowing visual confirmation of position.
Are these valves available in DIN or BS standards?
Yes. The series includes models compliant with DIN3202 and BS5163 standards, including PN10, PN16, and other pressure ratings.
What sizes are available in this family?
The metal seated gate valve series covers nominal diameters from DN10 to DN2600. Exact size and pressure rating per model are confirmed on request.
Can I get valves with metal seats for high-temperature service?
Yes. Metal seated gate valves are designed for high-temperature and high-pressure applications where elastomeric seats are unsuitable.
What certifications does the factory hold?
Tianjin MIC Valve Co., Ltd. holds ISO 9001 quality management and ISO 14001 environmental management system certification.
Do you supply mixed orders across valve types?
Yes. Metal seated gate valves can be shipped together with butterfly valves, check valves, strainers, and other types in a single container.
Can the valves be supplied with actuators?
Actuators are not included in standard supply. However, custom configurations with actuators can be arranged upon request.
