Who It Is For

Buyers This Category Suits

  • Water utility contractors sourcing isolation valves in bulk for municipal projects
  • Pump and skid builders requiring full bore flow with minimal pressure drop
  • Power and chemical plant engineers standardising on reliable shutoff valves
  • Valve distributors stocking a full range of gate valves across nominal diameters
  • EPC buyers packaging valves for water, heating, and industrial process systems
Problems Solved

What It Fixes on the Line

  • Existing gate valves in retrofit projects have limited face-to-face length and cannot fit between existing flanges
  • Rubber seats degrade in high-temperature or aggressive media, leading to premature leakage
  • Mixed brands across a plant create inventory complexity for spare discs and stems
  • Small and mid-sized gate valves are often quoted as non-standard items with long lead times
  • Buyers need a single supplier capable of covering both standard and large-diameter gate valves in one order
Advantages

Why Engineers Specify This Family

Full bore flow

Full bore flow: the disc lifts completely out of the flow path, minimising pressure loss and turbulence

Tight shutoff

Tight shutoff: resilient and metal seats provide reliable sealing under operating pressure

Standardised design

Standardised design: the same body accepts multiple disc types and stem configurations for different media

Actuation compatibility

Actuation compatibility: the rising stem allows for manual, gear, pneumatic or electric actuator mounting

Range coverage

Range coverage: the series spans DN10 to DN2600, covering small service lines to large industrial headers

Single source

Single source: all components including discs, stems, and seats are manufactured in-house under ISO 9001 and ISO 14001

Application Scenarios

Where These Valves Are Installed

  • Isolating feedwater lines in boiler systems where full bore flow is required
  • Shutting down process lines in chemical plants with aggressive or corrosive media
  • Controlling flow in district heating networks with low pressure and high reliability needs
  • Managing slurry and wastewater in sewage treatment plants using knife gate valve variants
  • Providing shutoff in fire protection risers where tight sealing is critical

FAQ

Gate Valves FAQ

What is the difference between resilient seated and metal seated gate valves?

Resilient seated valves use rubber or PTFE seats for tight shutoff in clean water and general service. Metal seated valves are used in high-temperature or high-pressure applications where rubber seats would fail.

Can I use a gate valve for throttling?

No. Gate valves are designed for on-off service only. Throttling causes seat and disc wear and leads to premature failure.

What sizes and pressures are available?

The gate valve series covers nominal diameters from DN10 to DN2600 mm and nominal pressures from 0.05 to 4.0 MPa. Exact size and pressure per model are confirmed on request.

Are actuators available for these valves?

Yes. Manual, gear, pneumatic, and electric actuators can be fitted and tested at the factory before shipment.

What certifications does the factory hold?

Tianjin MIC Valve Co., Ltd. holds ISO 9001 quality management and ISO 14001 environmental management certification. Test records for your order are issued on request.

Can I order mixed valve types in one shipment?

Yes. Gate valves, butterfly valves, check valves, joints, and strainers can be combined in a single container for project delivery.
