Key Design Features
The Through Conduit Slab Gate Valve incorporates several innovative features that enhance its efficiency and longevity:

Full Bore Port
The full-bore design allows for unrestricted flow, reducing pressure drop and enabling pigging operations without obstruction. This ensures best performance in transmission pipelines.

Double Block and Bleed Capability
This feature enhances safety by providing dual isolation on both upstream and downstream sides when the valve is fully closed. It allows for system maintenance without disrupting pipeline operations.

Protected Seat Sealing Faces
The seat sealing faces are fully protected from fluid contamination, ensuring a longer lifespan and maintaining a tight seal under various pressure conditions.

Tight Mechanical Seal for High and Low Pressure
Designed for both high and low-pressure applications, the Through Conduit Slab Gate Valve ensures a secure shutoff to prevent leakage and maintain pipeline integrity.

Internal Cavity Pressure Relief
A pressure relief mechanism prevents pressure build-up inside the valve body, reducing the risk of internal component damage and improving operational safety.

Sealant Injectors for Seats and Stem
Sealant injectors allow for additional lubrication and emergency sealing, ensuring continued performance even in demanding applications.

Bi-Directional Flow Capability
The Through Conduit Slab Gate Valve can handle bi-directional flow, making it versatile and suitable for various pipeline configurations.
