Manufacturing
One valve, four stages
Casting is done in house. A single size is traced against the same parts list from casting to test, and these four stages run in the same order for every product.
Body and bonnet casting
Bodies, bonnets and covers are cast in house, in bronze, steel and stainless alloys. The material is chosen for the medium and the pressure of the circuit.
Machined to the standard
Sealing faces, stem bearings and flange faces are machined, with tolerances checked against the dimension tables of the relevant standard.
Assembled to the parts list
Every valve is assembled to its own material list. Packing, stem and disc are selected for the temperature and pressure the product will work at.
Shell and seat testing
Products pass shell and seat tightness testing before dispatch, at the pressures the relevant standard prescribes.
Quality
Certification is part of manufacturing, not an outcome of it
The material a valve was cast from and the standard it was built to should always be traceable.
Type approved production
Products carry type approval from Türk Loydu, RMRS and RINA, and the quality management system is certified to ISO 9001.
Traceable material
The material used in every product is stated in the parts list together with its standard.
Documentation with the product
The technical drawing, the dimension table and the material list are delivered with the product.
Certification
Class approvals and the documents that ship with the product
Which society approved a valve, and which documents arrive with it, are the two things worth knowing before an order.
Class society approvals
Products carry type approval from Türk Loydu, RMRS and RINA. These approvals are about the product: they say the valve is fit for marine service.
Quality management system
ISO 9001 is about the company: how manufacturing is run, audited and recorded.
