Unique SSV Y-bodyConcept

The Unique Single Seat Y-body valve meets the highest demands of your process in terms of hygiene and safety. Built on the well-proven Unique SSV platform the Y-body version offers a straight through product flow path and is designed for gentle product treatment. The main use for these valves is in applications involving high viscosity or large particulates.

Working principle

The valve is a pneumatic seat valve in a hygienic and modular design remote-controlled by means of compressed air. It has few and simple moveable parts which results in a very reliable valve and low maintenance cost.

Standard design

The valve is designed to deliver years of reliability and performance as can be expected from all Alfa Laval products. The actuator is connected to the valve body using a yoke and all components are assembled with clamp rings.

Unique SSV Aseptic

Unique SSV Aseptic

Fully modular with the proven design of the Unique SSV the aseptic single seat valve is equipped with a hermetic sealing diaphragm that ensures true aseptic conditions during operation. It hermetically seals against intrusion from the atmosphere and ensures full protection against the effects of microorganisms.

With a “sandwich construction” of PTFE on the product side, EPDM and an enforcing mesh, the aseptic diaphragm is optimized to guarantee reliable performance and long lifetime. In open position the one-piece diaphragm is mechanically supported by the valve to reduce wear and increase endurance. The Unique SSV Aseptic valve is available in both pneumatic and manual configurations.
