Compliance with EN-593: Our Flange type butterfly valves comply with EN-593 regulations, which ensures their quality and efficiency in hydraulic applications.
Ductile Cast Iron Construction: Ductile cast iron construction provides these valves with robustness and durability, making them ideal for demanding environments.
Stainless steel closing Disc option: We offer the option of a stainless steel closing disc, which increases corrosion resistance and extends the useful life of the valve.
Mounting Length according to EN 558-1 and API 609: The mounting length of our valves conforms to EN 558-1 Series 20 and API 609 regulations, facilitating their integration into existing systems.
Top Flange according to ISO 5211: Flange type butterfly valves include a top flange that complies with ISO 5211 regulations, allowing the installation of actuators and other components in a simple way.
Mounting between flanges according to UNE-EN 1092-2: These valves are designed for mounting between flanges in compliance with the UNE-EN 1092-2 regulations in pressure classes PN10 and PN16.
Temperature Range with EPDM Elastomer: Our valves can operate at temperatures up to 100ºC with EPDM elastomer, making them suitable for applications where resistance to high temperatures is required.
CHARACTERISTICS:
– Easy installation.
– Total tightness and minimum pressure loss.

Aplications
Foot valves are commonly used in ponds, swimming pools, wells and almost anywhere there is a pump.
The surface or opening of the foot valve is larger than that of the pipe, thereby minimizing pressure loss (energy dissipated due to friction along the pipe).
Our double flange butterfly valve has been designed in a general way, for those situations where there are dimensional limitations. It has bolts on both sides, which allows the disassembly of one side of the installation while keeping the other under pressure and in full operation. It offers great facilities in assemblies that require temporary isolation of lines, such as pumps, tanks, naval installations, etc. The Double Flange valve generates minimal pressure loss thanks to the optimization of the disc profile.
It is a very popular quarter-turn, two-way, resilient-seated valve for on-off or modulating services. It is centered (concentric) whose axis is located in the center of the disc, which is centered on the inside with respect to the X, Y axes. The tightness is optimal and it is a suitable valve for low pressure ranges. It is light, takes up little installation space, has a lower cost, and works quickly. The disc is connected to a shaft that when the valve opens the disc rotates to allow the passage of fluid and closes when the shaft rotates the disc to a position perpendicular to the direction of flow.
We have a standard construction in the small and medium passages with a manual operation lever that allows the valve to be blocked in the open or closed position and in the large passages the standard operation is with a stress gear box. Both options are inexpensive and easy to handle.
We offer options for all steps with motorized actuators (single-phase or three-phase electric and double- or single-acting pneumatics) thanks to the fact that the flange on its upper part is in accordance with international standard ISO 5211, which specifies the requirements for fixing fraction actuators. back to industrial valves. These actuators are a reliable method of controlling the valve from a remote location as well as allowing large valves to be quickly actuated. Actuators can be mounted on the valve for fail-open (the valve is always open if the actuator fails), or fail-close (the valve is always closed if the actuator fails).
This butterfly valve is used for water treatment, wastewater, irrigation and in various industries and industrial applications. Not recommended for bulk solids.
IMPORTANT: Both during storage and when assembling it, the Butterfly valve must always be ajar, to avoid in the first case deformations of the elastic seat (elastomer) and during assembly to avoid tensions or forces that prevent proper centering and fastening that Do not close the valve properly.
