GATE VALVES

1️⃣ PRODUCT INTRODUCTION

VikTech Fittings is a trusted Supplier, Trader & Exporter of Gate Valves, providing reliable flow-isolation solutions for industrial piping systems, process plants, oil & gas facilities, petrochemical plants, power plants and engineering applications.

Gate Valves are designed primarily for fully opening or fully closing the flow of liquids, gases and other process media. They use a gate or wedge-shaped closure element that moves vertically to control the passage through the valve.

When fully open, Gate Valves provide a relatively unobstructed flow path, making them suitable for applications where minimum pressure loss and reliable isolation are required.

VikTech Fittings supplies Gate Valves in different materials, sizes, pressure classes, bonnet designs, end connections and operating configurations according to customer requirements, applicable standards and project specifications.

5️⃣ TYPES OF GATE VALVES

WEDGE GATE VALVES

Wedge Gate Valves use a wedge-shaped gate to provide reliable isolation.

✓ Solid Wedge
✓ Flexible Wedge
✓ Split Wedge
✓ Suitable for Industrial Piping
✓ Available in Cast and Forged Construction

PARALLEL SLIDE GATE VALVES

Parallel Slide Gate Valves use parallel gate discs and are commonly used in applications requiring reliable isolation.

✓ Suitable for High-Pressure Service
✓ Suitable for Steam Applications
✓ Low Operating Torque
✓ Available in Forged and Cast Construction

RISING STEM GATE VALVES

The stem moves upward as the valve is opened, providing a visible indication of valve position.

NON-RISING STEM GATE VALVES

The stem remains within the valve body while operating, making this configuration suitable where installation space is limited.

FORGED GATE VALVES

Forged Gate Valves are commonly used for high-pressure and high-temperature applications, particularly in process and energy industries.

CAST STEEL GATE VALVES

Cast Steel Gate Valves are available in a wide range of sizes and pressure classes for industrial piping applications.
