Simmel Butterfly Valve

High-performance wafer butterfly valve (NPS 1.5-24/DN 40-600) featuring zero leakage sealing, low flow resistance, and clamp-on installation. Ideal for industrial piping systems.

High-performance wafer lug butterfly valve with 100% bi-directional bubble tight shut off. Ideal for shipbuilding, petrochemical, water treatment & heavy industries. Compliant with BS EN-593 & ISO standards.

High-performance flange butterfly valve with centerline elastic seal for near-zero leakage, low flow resistance & easy maintenance. Ideal for water, air & oil applications.

SIMMEL high-performance butterfly valve is a new type of butterfly valve designed based on the advantages of several different structural butterfly valves.
The sealing surface of the valve plate of this butterfly valve is a spherical arc body, and the sealing mechanism achieves a true dynamic seal through system pressure.
Therefore, it has excellent cutting performance, long service life, and low torque characteristics.
The product is suitable for various working conditions, especially for gas transportation.
In process media with high working temperature and high valve life requirements, the normal service life can reach about 1 million times.
The tighter the flange clamp on the insert outside the valve seat, the greater the pressure, and the better the sealing performance.
This butterfly valve has a unique product structure and ultra reliable sealing performance.
