Approve the valve once. Keep the equipment build repeatable.
HHSV supports OEM programs where installation fit, fixed drawings, stable BOMs, batch consistency and repeat-order control matter as much as the first valve selection.
Build around a controlled technical baseline.
Repeatable dimensions
Keep inlet/outlet connections, envelope dimensions and installation interfaces tied to the approved configuration.
Stable BOM
Control material, trim, spring, seals and configuration so repeat orders do not drift from the approved build.
Batch consistency
Carry material, serial-number and test traceability through batch production and documentation.
Schedule & cost
Separate engineering approval from repeat-production supply so recurring orders can be planned against a known baseline.
Start with the protected equipment and service conditions.
Product families shown below are common evaluation starting points, not automatic selections. Final valve architecture depends on sizing, service data and applicable standards.
Boilers & Steam Equipment
Steam relief duties where set pressure, capacity, temperature and the applicable code scope must be confirmed.
Pressure Vessels
Gas, steam or liquid pressure protection requiring repeatable connections and equipment integration.
Compressor Packages
Gas-service protection where operating ratio, backpressure and package layout can influence selection.
Tanks & Process Skids
Packaged systems that may combine positive-pressure relief, vacuum/breathing protection or accessories.
Freeze what must repeat; review what actually changes.
Standardized series selection
Use a defined series/configuration for recurring equipment only after the actual service conditions and sizing basis are confirmed.
Fixed installation baseline
Approve GA dimensions, connections and installation envelope before turning the selection into a recurring build.
Approved bill of materials
Hold materials and configuration to the approved baseline; route genuine changes back through engineering approval.
Material & serial records
Maintain material/heat and valve identification records at the level required by the order.
Batch verification
Apply the required inspection and performance-test scope to production batches and retain applicable records.
Batch / call-off orders
Plan repeat or call-off supply against an agreed technical baseline, quantity and delivery schedule.
Move from one approved build to controlled repeat production.
Design
Collect service data, equipment interface, capacity, materials, standards and target production requirements.
Approval
Complete sizing and approve the selected series, datasheet, GA drawing, BOM baseline and required documents.
Prototype / first batch
Manufacture and inspect the first supply against the approved baseline; close any genuine design changes.
Repeat production
Use the controlled configuration for scheduled batches, call-offs or repeat purchase orders.
Documentation
Deliver required material, traceability, test and conformity records with the applicable production batch.
Choose the architecture by duty, not by equipment label alone.
Spring-Loaded
Direct spring-loaded configurations for a broad range of pressure-relief duties.
Pilot-Operated
Pilot/main-valve architecture evaluated where the service conditions justify it.
Vacuum & Breather
Negative-pressure protection and equipment/tank breathing applications.
Accessories & Combinations
Protection-system accessories and combinations when the system layout requires them.
A repeat order should identify the same approved valve—not restart engineering from memory.
Reference the previous series, approved drawing/BOM, order record and any controlled revision. If service data or equipment design changes, return the affected item to technical review before production.
Engineering & Sizing
Convert service conditions into a calculable, reviewable valve selection.
Send the service data and equipment interface together.
Include capacity, pressures, temperature, backpressure, medium, connections, materials, standards, annual/batch quantity and the drawings or document requirements that must remain repeatable.
