Import Breather Valves — Buy in Bulk from Supplier in United Kingdom

The MTP Opti-Flow 380 Series Breather Valves from Motherwell Tank Protection are direct-acting pressure relief valves designed to protect storage tanks and process vessels from excessive pressure and vacuum conditions. These valves operate without external power, relying on precision-set spring mechanisms to open at calibrated pressure differentials and reseal automatically once conditions normalise. The series handles a range of pressure settings suitable for diverse industrial applications, with metal-to-metal or resilient seating options depending on service requirements. Construction is typically realised in materials compatible with petroleum vapours, chemical gases, and ambient atmospheric conditions typical of tank farm environments.

The valve bodies are typically cast from aluminium, ductile iron, or stainless steel, with trim components in stainless steel to resist corrosion from aggressive media. Seating surfaces are lapped to achieve bubble-tight shutoff, minimising product loss and emissions to atmosphere. Spring materials are selected for temperature stability across the operating range, with options for low-temperature or high-temperature service. The compact footprint allows installation on standard tank roof nozzles without structural modification, and the weight-loaded or spring-loaded pallet designs accommodate varying flow requirements. Standard industry practice includes epoxy or polyurethane coatings for environmental protection in marine and coastal installations.

Primary buyers include operators of bulk liquid storage terminals, refineries, chemical plants, and food-grade tank installations where vapour management is regulated under environmental permits. The valves serve critical safety functions in floating roof tanks, fixed roof tanks, and process vessels handling volatile organic compounds. Trade terms typically involve FOB or CIF shipment from UK ports, with packaging in timber crates or reinforced cardboard to prevent seat damage during transit. Buyers should confirm pressure and vacuum settings, flange drilling standards, and material certifications directly with Motherwell Tank Protection before finalising specifications.

The listing presents Motherwell Tank Protection as the source of the MTP Opti-Flow 380 Series, a branded product line with defined model nomenclature suggesting in-house engineering rather than pure trading. No employee count, annual turnover, factory size, or client references are stated in the source material, and these should not be inferred. The company does not claim ISO 9001, ATEX, or PED certification explicitly in the provided data, and any such assertions must be requested directly from the supplier with certificate numbers and scope. Buyers are advised to verify the legal entity name, , and registration details before issuing purchase orders, and to request witness testing or third-party inspection if certification is a procurement requirement.
