RESILENT WEDGE GATE VALVE - SHORT BODY (UNI/DIN/BS )

Elastic wedge gate valve - short body (UNI/DIN/BS) is a type of gate valve with a disc covered with elastic rubber (usually using EPDM), which helps to completely close and prevent leaks. Unlike long-stem types, short-stem valves have shorter mask distances (according to EN 558 Series 13 standards), helping to save mounting space and costs while still ensuring high tightness and durability.

Basic Concept

Resilient Seated Gate Valve: The gate is coated with resilient rubber (commonly EPDM), which compresses against the seat when closed to achieve bubble-tight sealing.
Short Body: Shorter face-to-face dimension, according to EN 558 Series 13, making it suitable for installations with limited space.
Connection standards: UNI/DIN/BS/ISO – ensuring international compatibility.
Applications: Urban water supply systems, water treatment plants, chemical industry, food industry, fire protection systems.
