Belgicast Soft Sealing Gate Valves

Product catalog summary

Specifications:
The soft sealing gate valves are constructed from spherical graphite cast iron EN-GJS-500-7 (GGG-50) with a blue RAL 5015 epoxy powder coating. The wedge is similarly constructed and can be coated with EPDM or NBR. The stem is typically made from stainless steel AISI-420, with options for AISI-316. The valves feature a body-bonnet gasket in EPDM or NBR and are bolted with carbon or stainless steel. Standard operation is clockwise closing, with an option for clockwise opening.

Manufacturing Program:
The program includes various types of soft sealing gate valves, such as F4-F5, BS, PN-25, and those with flanged ends. Sizes range from DN40 to DN1200, with configurations for applications like fire protection and underground installation.

Valve Testing:
Testing follows EN 12266-1 and EN 1074 standards, with shell tightness tested at 1.5 times allowable pressure and seat tightness at 1.1 times. Valves are tested for zero leakage (Rate A) and are suitable for pressures up to 25 kg/cm² and temperatures from -10°C to 50°C.

Quality Control:
All valves undergo 100% testing according to relevant standards, ensuring endurance resistance for 2,500 cycles. Compliance with ISO, UNE, DIN, NF, BS, and AWWA standards is ensured.

Applications:
Suitable for potable water, sewage, seawater, HVAC, industrial processes, irrigation, fire protection, and vacuum applications.

Operating Torque:
The operating torque complies with EN 1074 standards, with specific torque values for different DN sizes. A safety factor of 1.3 is recommended for actuator selection.

Approvals:
The products are approved by organizations such as ISO, NF, KIWA, DVGW, WRAS, ÖVGW, GOST, FM, and VDS, ensuring suitability for drinking water.

Materials and Components:
The valves consist of components like the body, bonnet, wedge, stem, and gaskets, made from materials such as EN-GJS-500-7, EPDM, copper alloy, and stainless steel, adhering to standards like EN 1563 and EN 681-1.

Design Features:
Belgi-3 and Belgi-4 valve assemblies are compact with easily replaceable components and anticorrosion protection. They are customizable and include eye-bolts and mounting feet for easy handling.

Installation and Operation:
Valves should be stored with the rubber wedge slightly open. During installation, avoid transmitting pipe stresses to the valve body. Valves can be installed independently of flow direction and should be tightened in a star-shaped pattern. Use MOLYCOTE or similar grease on bolts to prevent corrosion.

Recommended Positions:
For DN40 to DN300, the ideal position is a vertical stem with horizontal flow. For DN350 to DN1200, a vertical stem with horizontal flow is ideal, but horizontal flow is acceptable. Horizontal stem with vertical flow is not recommended for larger sizes.

Usage Limitations:
Valves should not be used for regulating flow or with gaseous fluids like propane, butane, or natural gas. They are suitable for potable water transmission, sewage treatment, and HVAC installations.

Company Information:
BELGICAST Internacional, S.L. is part of the TALIS Group, specializing in water transport and flow control solutions, offering a wide range of products for water and energy management.
