Quick-Action Lever Wafer Rising Stem Round Port Knife Gate Valve

Lightweight, Instant Isolation for Quick Process Control

This Knife Gate Valve is the ideal choice for small-to-medium pipeline systems requiring rapid, full isolation and high operational speed. It replaces the slow handwheel with a Quick-Action Lever, allowing the valve to be fully cycled (opened or closed) in moments with a single manual motion, which is crucial for quick process adjustments or safety shut-offs.

The Wafer body style provides a compact, lightweight design that simply clamps between pipeline flanges, offering significant savings in space and installation time. The Rising Stem provides clear visual confirmation, ensuring operators know the exact position of the gate at a glance.

Key Features & Operational Advantages

Feature Category	Technical Detail	Core Operational Benefit
Operation Speed	Quick-Action Lever	Provides near-instantaneous opening and closing, drastically reducing cycle time compared to gear or handwheel mechanisms, vital for time-sensitive applications.
Installation Ease	Wafer Pattern Body	Lightweight and compact, fitting directly between existing pipeline flanges, requiring fewer bolts and simplifying installation and alignment.
Safety Indication	Rising Stem Design	The visible movement of the stem offers immediate, clear confirmation of the valve’s open/closed status.
Design	Direct Linkage Mechanism	Simple, robust linkage connects the lever directly to the stem, ensuring high reliability and minimal component count.
Structure	Bonnetless Design (Standard)	Prevents solid material from packing into the bonnet cavity, ensuring the gate and linkage operate reliably.
Flow Path	Round Port	Ensures smooth, unobstructed flow when open, minimizing pressure loss and turbulence.

Target Industry Applications

This valve is ideal for smaller lines that demand frequent, fast operation:

Utility & Water Treatment: Quick isolation on clean water, utility service lines, and chemical feed lines.
Process Sampling: Used as a reliable and fast shut-off valve on sample points and laboratory feed lines.
Manufacturing: Fast control of cooling water, drain lines, and low-viscosity process fluids.

Note: The Quick-Action Lever design is most effective for smaller valve sizes where the closing force required is minimal.
