Overview

The APV DP4 line of double seat mix proof valves enables product recovery or pigging through a mix proof valve body. By using a pig to recover product and reduce soil, we're able to save volume of cleaning fluid, as well as time during CIP. 

High Value, Low Life Cycle Costs: 

• The use of pig for product recovery means less product loss and greater yield

• Pig use descreases downtime arelated to sleaning and the costs associated with watewater and CIP fluid 
• Lower air consumption and air supply requirements 
• Leak drain with clamp connection for CIP fluid collection
• Long housing ports ease manifold building 

Reliable Performance 

The DP4 is: 

• Based on the proven D4SL model 

• Features a long stroke for gentle product handling and low flow resistance

• Balanced design of lower shafts helps prevent hydraulic blocking and enables flexible flow direction without slamming

• No copmressed air needed for removal and servicing

• Range of control units and bus communication for automated operation
