DT4 Series - Tank Outlet Double Seat Mixproof Valves

The DT4 tank outlet mixproof valve is used for the reliable separation between the tank and servicing pipeline. The DT4 tank outlet is an extension to the D4 Series mixproof family which helps fulfil today’s customer demands for production flexibility, increased productivity, rapid return on investment (ROI) and improved product quality in the food and drink, dairy, personal care and brewing process industries.

Features & Benefits

High Value, 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 such as one kit for 1.5” - 3.0” sizes
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

Design based on the proven D4SL model
Tank side holding pressure greater than 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

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
