Featured SpecsView CategoryEvery product in this catalog is specified against a known pressure class, seat material and body metallurgy — the same reference our engineers use when matching a component to your application.
Pressure Classes
Working pressure ranges across our standard and high-pressure ranges — the starting point for matching a component to your process conditions.
| Series | Scope |
|---|---|
| 6K / 10K / 15K / 20K psig | SS316 across ball, needle, manifolds and DBB — standard instrumentation classes |
| MP Cone & Thread — 20,000 psi | Compact, weld-free sealing for very high pressure or tight envelopes |
| HP Cone & Thread — 60,000 psi | Proven for hydrogen and offshore service; HP needle valves extend to this class |
Seat & Seal Materials
Seat and packing material governs temperature range and chemical compatibility — selected per application during quoting.
| Material | Notes |
|---|---|
| PTFE | Broad chemical resistance, typical to ~200°C. Standard for many ball seats and needle packing. |
| PEEK | Higher temperature and deformation resistance; suited to higher delta-P and compressible gas service. |
| KEL-F (PCTFE) | Cryogenic and low-temperature service with good permeation resistance. |
| Graphoil | High-temperature packing to 538°C in needle and manifold bonnets. |
Body Metallurgy
Body material is matched to the media and environment — from standard utility service to aggressive offshore and chemical duty.
| Material | Application |
|---|---|
| SS316 | Standard choice for most utilities and clean process streams |
| Duplex | Higher strength and chloride stress corrosion resistance; common offshore |
| Monel | Excellent seawater and hydrofluoric acid resistance |
| Hastelloy | Aggressive chemical resistance in refining and chemical plants |
Our standard range covers SS316 for general process and utility service, with Duplex and Super Duplex available for higher strength and chloride/stress-corrosion resistance. For aggressive chemical service we also supply Monel, Hastelloy and Inconel across valves, manifolds and fittings.
Yes. Most valve, manifold and fitting ranges support our online Product Configurator — choose end connections, materials, pressure ratings and certifications, then add your exact build straight to an order.
Standard components ship from UK stock within 24-48 hours. Bespoke or configured products get a firm lead time during quoting, based on materials, certification requirements and order volume.
Our quality management system is certified to ISO 9001:2015, ISO 14001:2015 and ISO 45001:2018. We hold ATEX and CE PED marking for tube fittings and are a registered BFPA member — full certificates are available on request.
Yes — apply for a trade credit account to streamline repeat ordering and invoicing. You can start an application any time from the 'Apply for Credit' link in the site header.
Every order includes access to full technical documentation: our Catalog Library, 2D/3D drawings and CAD files ready for direct import into your design workflow.
