DTC‑GATE VALVE‑DI Series
DTC supplies industrial gate valves designed for reliable shut-off service in oil & gas, water treatment, power generation, and process piping systems. Available in cast steel, stainless steel, and alloy materials with flanged, rising stem, and wedge gate designs.
An industrial gate valve is a linear motion valve designed primarily for fully opening or fully closing fluid flow in pipelines. It uses a gate-shaped disc that moves vertically to control the passage of liquids or gases.
Unlike globe valves, which are mainly used for flow regulation, gate valves are designed for minimum pressure drop and full-bore flow performance when fully open. They are widely used in pipelines where reliable isolation and long service life are required.
DTC supplies industrial gate valves for demanding applications including oil & gas pipelines, petrochemical plants, power stations, water treatment facilities, and industrial process systems.
Our gate valves are available in:
When fully opened, the gate provides a straight flow passage with minimal pressure loss.
Designed for tight sealing and dependable isolation in industrial piping systems.
Suitable for medium and high-pressure applications.
Manufactured using quality cast or forged materials for long service life.
Designed for long-term operation with minimal maintenance requirements.

A rising stem gate valve has a stem that moves upward when the valve opens.
The stem rotates without moving vertically.
The wedge-shaped gate provides sealing between two inclined seats.
Uses an elastomer-covered gate for improved sealing.

An industrial gate valve is mainly used to completely open or close pipeline flow in industrial systems.
Gate valves are not recommended for throttling because partial opening may cause vibration, erosion, and sealing damage.
A rising stem valve shows the valve position through stem movement, while a non-rising stem design saves installation space.
Common standards include API 600, API 6D, ASME B16.34, and API 598.
