Engineered and manufactured in China for industrial projects worldwide

Application & engineering

Process & materials

Share the medium and operating range so we can review the ceramic, body, packing, gaskets and other wetted materials

Medium
Composition, concentration, liquid or gas phase and cleaning media
Operating range
Normal and maximum temperature, pressure and thermal cycles
Solids
Particle size, hardness, concentration and any settling or crystallization
Sizing & control

Flow range and pressure drop guide sizing. We review the risk of erosion, cavitation and flashing alongside the required control performance

Flow
Minimum, normal and maximum flow, pressure drop and required Cv
Valve duty
Isolation or regulation, shutoff requirements, cycling frequency and minimum opening
Actuation
Air or power supply, control signal, fail position, feedback and stroke time
Installation & documentation

Confirm the installation and document requirements before the valve configuration is finalized

Connections
Nominal size, pressure class, flange standard, facing and face-to-face dimensions
Installation
Flow direction, pipe support, actuator clearance and maintenance access
Delivery scope
Drawings, material requirements, inspection criteria and the document list
Drawing requests
Powder feed & discharge

For powder duties, include bulk density, moisture, bridging or compaction, conveying gas, backpressure and feed rate. These help us review the opening, sealing arrangement and discharge conditions

Packing
Materials & dimensionsReview material records and inspect critical dimensions

Incoming material checks and component inspection support the agreed specification before assembly

  • Material identification and records
  • Machined dimensions and ceramic surfaces
  • Fit and condition of mating components
Assembly & checksValve and actuator checks

After assembly, pressure tests and actuator checks follow the scope and acceptance criteria agreed for your order

  • Pressure and sealing checks
  • Valve and actuator operation
  • Product identification and traceability
Testing questions
Prepare for dispatchCheck the finished valve and the agreed delivery documents

Review the valve identification, packing and project document list before dispatch. Agree any inspection or witnessing requirements with us when placing the order
