SPX FLOW D4 Mix Proof Valve Overview

High Value with Low Life Cycle Costs

“All-In” standard features such as seat lift actuator and cross-port housing provide exceptional value
Reduced inventory costs with same seal kit used on multiple size ranges: DN40-DN65 (1.5”-3.0”) and DN80-DN100 (4.0”)
Low air consumption and air supply requirements
Leak drain with clamp connection for CIP fluid collection
Long housing ports ease manifold building
Integrated shaft seal flush reduces need for external piping

Reliable Performance and Engineering

Design based on the proven D4SL model
Tank side holding pressure greater than 5 bar (73 PSI)
Long stroke for gentle product handling (ex: particulates) and low flow resistance
Balanced design helps to prevent hydraulic blocking and enables flexible flow direction without slamming
Heavy-duty bolted flange connection between tank/housing/insert provides secure, controlled assembly/disassembly of valve insert
No compressed air needed for removal and servicing
Range of control units and bus communication for automated operation

Cleanability and Hygienic Design

Advanced Sanitary Features

Designed to the latest global hygienic standards
Cavity spray cleaning as standard
Radial seal design provides minimal switching leakage
Extensive cleaning of product contact seals
