The 1″ nominal bore check valve has an operating pressure rating up to are up to 15,000psi [1034bar] with an operating temperature range of -20F[-29C] to +350F[+177C].

Subsea Relief Valves have a cracking pressure of 10 psi to 20 psi and a reverse sealing pressure Test (hyperbaric) of up to 5,000psi.

We produces a range of small bore block or panel mounted subsea High-Pressure High Temperature (HPHT) needle valves with a bore size of 0.30” [7.6mm] bore.

We supplies an extensive range of ROV receptacles and Position Indication systems for use with our own valves and other subsea equipment such as electrical penetrators and small bore gate valves.

We provides fluid control solutions for pre- and post-combustion carbon capture applications. Hydcovalves products are based on years of experience in developing and supplying cost-effective, high-reliability doors and pipeline ball valves in the oil and gas industry.

We provides valve products designed for low-carbon hydropower production, covering the entire process of fossil fuels to make blue hydrogen and electrolytic to make green hydrogen.

The 'HD' Type Single Isolating Needle Valve is designed for safe and reliable isolation. It provides a bubble-tight shutoff, a non-rotating and anti-galling tip, and a dynamic self-adjusting spindle seal to deliver a long service life in various high-temperature and high-pressure applications.

Our flange double-blocking bleed (DBB) valves offer two- and three-piece body designs that integrate the functionality of three valves into a single unit, reducing weight and saving the entire installation space. The two-piece design offers Oliver-compliant lengths (to ASME Class 300) and ASME B16.10 lengths (for ASME Class 600 and above). All valves in the three-piece design use the shortest total length of Oliver.
We also offer a variety of other bleed valve options and are able to work with our customers to take a technical project-centric approach to ensure full compatibility.

Our compact double cutoff discharge (DBB) valves have a total length designed to comply with ASME B16.10 standards. The monocoque valve body design reduces potential leakage paths and keeps weight and space to a minimum. Two specifications are available in full diameter and shrinkage diameter.
