Through Conduit Slab Gate Valve

Overview

Through Conduit Slab Gate Valves are engineered for full-bore, bi-directional shut-off in high-pressure pipelines, making them essential for oil & gas transmission, isolation, and metering systems. Designed in compliance with API 6D, these valves minimize pressure drop, reduce turbulence, and offer zero-leakage sealing — making them ideal for critical pipeline operations across Saudi Arabia.

With massive investment in pipeline infrastructure and energy transmission, Saudi Arabia requires API 6D-compliant gate valves that meet Aramco, SABIC, and SEC standards. This guide covers the top manufacturers and suppliers offering through conduit slab gate valves locally.

What is a Through Conduit Slab Gate Valve?

A Through Conduit Slab Gate Valve uses a solid gate (slab) that slides across the flow path to shut off flow. When fully open, the gate aligns with the bore, allowing unrestricted, piggable flow. These valves are ideal for liquids, gases, and crude oil, especially in long-distance pipelines.

Key Features:

• Full bore / through conduit design (pigging-compatible)

• Slab gate with floating or fixed seats

• Bi-directional sealing

• Low operating torque

• Suitable for Class 150 – 2500 service
