BVALVE replacement components, bellows cartridges and repair kits

To maintain continuous operation across flow systems, BVALVE supplies dedicated bellows repair sets, replacement plugs, graphite packings and actuator diaphragms. Prompt technical selection by serial nameplate restores factory sealing performance without downtime.

  • Replacement 1.4571 multi-ply bellows assemblies and precision profiling plugs
  • High-density sealing ring sets made from pure graphite and heavy-duty Gylon
  • Pneumatic actuator repair kits including durable diaphragms and return springs
  • LESER safety valve replacement trim components, calibrated springs and discs

Spanish engineering heritage and manufacturing facilities of BVALVE in Valencia

Spanish engineering company Bvalve Flow Systems & Controls has developed robust fluid control valves for industrial pipelines since 1996.

The central manufacturing campus in El Puig covers 1,800 square meters of technical offices and 4,400 square meters of assembly workshops, incorporating an accredited calibration facility and flow test equipment.

BVALVE engineers fluid handling units for chemical, power generation, refining and pharmaceutical plants. Factory production conforms to ISO 9001 quality management guidelines and the European Pressure Equipment Directive PED 97/23 EC.

Strategic warehouse reserves in Spain ensure rapid assembly and dispatch of standardized industrial valves and components.

BVALVE GS sliding gate control valves and severe duty globe units

BVALVE GS1 and GS3 sliding gate control valves utilize two sliding plates with precision-machined metering orifices that slide across each other. The tungsten carbide and stainless alloy plates provide exceptional wear resistance with equal percentage or linear throttling contours.

The compact wafer housing weighs significantly less than traditional globe valves.

GS control valves provide optimal regulation for steam, gases and aggressive chemicals across industrial process piping. For power station boiler feeds, BVALVE offers balanced globe control valves with multi-stage anti-cavitation trim.

Actuation options include multi-spring pneumatic diaphragm actuators and digital positioners communicating via HART protocols.

BVALVE 25065-66 bellows sealed valves for high temperature steam and thermal oil

BVALVE 25065-66 bellows sealed globe valves are purpose-built for thermal oil loops, steam distribution and toxic process media.

The core assembly features a multi-ply stainless steel 1.4571 bellows welded to the bonnet, isolating the moving stem from line fluids and eliminating atmospheric fugitive emissions common with standard gland packings.

The welded bonnet architecture ensures full joint integrity under thermal cycles up to 450 degrees Celsius. Valve bodies are manufactured from carbon steel GS-C25 and stainless steel 1.4408.

BVALVE fits these valves with linear regulating plugs for flow balancing, supported by pure graphite secondary packings and optional Gylon soft seating inserts.

BVALVE and LESER safety relief valves to API 526, ASME and DIN standards

In partnership with LESER, BVALVE provides full-lift spring loaded and pilot operated safety relief valves for industrial pressure vessels and boilers.

Fully qualified under API 526, ASME Section VIII and DIN standards, these units accommodate set relief pressures from 0.1 to 700 bar, safely releasing excessive volume during thermal or operational overpressure events.

Corrosive chemical duties utilize wetted components machined from Hastelloy, Duplex and nickel alloys. Clean Service designs feature dead-leg-free geometries tailored for pharmaceutical and food production.

Furthermore, BVALVE supplies 310/311 changeover valve systems enabling safe online maintenance of dual safety valves without shutting down live plant units.

SAFEFLEX KX triple eccentric butterfly valves and forged steel ball valves

SAFEFLEX KX triple eccentric butterfly valves are engineered for zero-leakage shutoff under demanding thermal and mechanical pressures. The triple offset shaft configuration eliminates rubbing between disc and seat ring during operation: metal-to-metal contact occurs only at final closure.

This geometry prevents seat wear and extends operating lifespans across plants.

SAFEFLEX KX valves deliver bi-directional tightness to Class A and satisfy Fire-Safe standards under API 607. Housing styles comprise wafer, lugged and double-flanged bodies up to DN 1200 dimensions.

For high-pressure isolation lines, the portfolio also incorporates Starline forged ball valves capable of handling volatile hydrocarbons and cryogenic fluids.

Maintenance guidelines, replacement trim parts and bellows repair kits BVALVE

To maintain design performance throughout the lifecycle of BVALVE installations, routine inspection and timely refurbishment of wear components are recommended.

Factory service kits include multi-ply stainless steel bellows cartridges, regulating plugs, precision seat rings, pure graphite packing sets and spiral wound gaskets matched to original tolerances.

Selection of parts is handled by technical specialists using the stamped nameplate data along with fluid parameters and pressure differentials.

For pneumatic actuators, replacement fabric-reinforced rubber diaphragms, return springs, NAMUR solenoid valves and limit switches are supplied, restoring factory sealing integrity across flow networks.
