Product Description

FYL Rising Stem Metal Seat Gate Valve is engineered to control fluid flow through pipelines by lifting or lowering a gate. When fully open, the gate is completely removed from the flow path, minimizing resistance and pressure loss. The rising stem structure allows operators to visually confirm valve status, improving operational safety and efficiency.

How It Works

The Rising Stem Metal Seat Gate Valve operates through a threaded stem connected to the gate. As the handwheel rotates:

The stem moves upward or downward along with the gate
The gate lifts to allow flow or lowers to block it
The visible stem position clearly indicates open or closed status

Core Structural Features

Rising Stem Design: External stem movement provides direct visual indication
Metal Seat Sealing: Ensures reliable sealing under high temperature and pressure
Full Bore Passage: Reduces turbulence and pressure drop
Robust Body Material: Suitable for demanding industrial environments

Product Advantages

Clear Operation Visibility: The rising stem structure allows operators to easily confirm valve position, reducing operational errors
Durable Metal Seat: High wear resistance, suitable for long-term use in harsh environments
Reliable Sealing Performance: Precision-machined sealing surfaces help minimize leakage risks
Low Flow Resistance: Fully open state ensures smooth flow with minimal pressure loss
Wide Media Compatibility: Suitable for water, steam, oil, and certain corrosive fluids

Technical Advantages

Advanced casting and machining processes ensure dimensional accuracy
Strict quality inspection before delivery
Support for multiple standards (API, DIN, BS upon request)
Optional anti-corrosion coatings for extended service life
