DESCRIPTION

Why Choose Metal Seated Ball Valves?

Traditional soft-seated ball valves use PTFE or NBR materials. These materials perform well in clean and moderate conditions but fail under extreme environments such as heat, slurry, or grit.

A Metal Seated Ball Valve solves these limitations with stronger sealing and longer service life.

Key Advantages

Zero-leakage performance improves production efficiency
Longer service life reduces maintenance and replacement costs
Designed for harsh and abrasive environments
Stable performance under high and low temperatures
High safety and reliability in critical systems
Custom-engineered solutions for different industries

At GMK VALVE, every valve is designed based on specific customer requirements to ensure optimal performance in real working conditions.

Key Features of Metal Seated Ball Valves

Our Metal Seated Ball Valve design includes advanced engineering features to ensure durability and safety:

Two-piece or three-piece body construction
Floating ball or trunnion-mounted design
Anti-blowout stem for safety
Full bore or reduced bore options
Fire-safe and anti-static design
ISO 5211 actuator mounting available
NACE MR0175 compliance for sour service
Spring-loaded metal seat for reliable sealing
Anti-stick design for high-temperature operation

High Temperature Stability

The valve seat uses a spring-loaded compensating structure, which keeps constant contact with the ball. This design prevents thermal expansion from causing valve sticking or seizure.

Even under high temperatures, the valve can open and close smoothly.

Advanced Sealing Technology

The metal-to-metal sealing system ensures:

Tight sealing under low and high pressure
Stable performance in extreme conditions
Resistance to wear and thermal deformation
Long service life of both seat and ball

The precision-machined ball and high-hardness seat ensure consistent sealing performance even after long-term operation.

Fire Safety and Anti-Static Protection

Safety is a critical requirement in industrial applications.

Our Metal Seated Ball Valve includes:

Fire-safe design (API 607 / API 6FA)
Anti-static device for explosion prevention
Reliable sealing under emergency conditions

This ensures safe operation in oil, gas, and chemical environments.
