API600 Handwheel Operated Gate Vavle
Our API600 Handwheel Operated Gate Valve requirement designed to meet the needs of industrial countries such as oil, gas, petrochemicals and power generation is a reliable solution. These valves may ensure a steady flow and control, even in a high-pressure and high-temperature environment, while complying with API600 direct standards, specially designed for sustainability and precision.
Comprehensive Overview
Definition & Application
A gate valve is a common linear-motion valve used in both above-ground and
underground pipelines.
These valves are also referred to as "sluice valves" or simply "gate valves."
Design & Operation
Structure:
Consists of a valve body (installed inline in the pipeline) and a handwheel actuator for opening/closing.
The multi-turn handwheel is mounted above or to the side of the valve, connected via a stem to the bonnet assembly.
Operation:
Open: Rotate the handwheel clockwise to raise the gate.
Close: Rotate counterclockwise to lower the gate and block flow.
Advantages
1. Full Flow Shutoff
2. Bidirectional Sealing
Blocks flow equally effectively in upstream and downstream directions.
3. Low Pressure Drop
Minimal pressure loss when fully open due to straight-through flow path.

Explanation |
|
Linear-Motion Valve |
Opens/closes via vertical gate movement (vs. rotary valves like ball valves). |
|
Handwheel Actuator |
Manual multi-turn operating mechanism. |
|
Bonnet Assembly |
Encloses the stem and ensures leak-proof operation. |
|
Bidirectional Sealing |
Seals flow from either direction (no preferred flow orientation). |
