RUF3 Series - Check Valves

The RUF Series Check Valve is used in places where a return flow of product in pipelines must be avoided. This check valve is utilized in brewery, dairy, chemical and pharmaceutical processing.

RUF3 Check Valve Overview

Optimized for Reliable Performance

Robust bearing and minimal parts reduce maintenance costs
Flexible installation in horizontal or vertical orientation
Intermediate flange design allows easy removal from pipeline
Profile seals with ID markings prevent gaps and simplify spare parts ordering

Flow Efficiency and Pressure Characteristics

Minimal flow resistance and pressure drop for smooth operation
Ball-shaped valve body ensures consistent fluid flow
Responds at low pressure: 0.72 psi (0.05 bar)
Fully open at just 1.16 psi (0.08 bar)

Sanitary and System Integration Features

Designed for CIP (Clean-in-Place) cleaning processes
Soft seat seal ensures leak-tight operation
Direct welding compatibility for streamlined system integration

Actuator Warranty & Reliability

The actuator supplied with this valve is covered by a 5-year actuator warranty, or up to 1 million actuations, whichever comes first. Built with fully welded, sealed, maintenance-free construction, it eliminates internal servicing and reduces wear components to deliver long-term durability in demanding hygienic processing environments.

Key benefits include:

Maintenance-free operation with no internal servicing
Fewer spare parts and improved total cost of ownership
uptime and production continuity
