HOKE Relief Valves Distributor in India

Priminox Overseas is the official distributor of HOKE R6000 series right-angle relief valves in Mumbai, India. HOKE relief valves vent excess line pressure once the system crosses a pre-set cracking value, protecting downstream instruments, vessels, and pipework from overpressure damage. We stock the LR6000, MR6000, HR6000, and XR6000 models, covering low, medium, high, and extra high-pressure duty in a single right-angle body footprint. Every body is 316 Stainless Steel, every spring is 17-7PH CRES, cracking pressures span 5 psig to 6,000 psig (0 to 414 bar) across the four models, and PED 97/23/EC certification with CE marking is standard on every part number.

Explore the Full Series of HOKE R6000 Relief Valves

The range covers four right-angle models built on a common 316 Stainless Steel body, the same 1/4 inch connection footprint, and 17-7PH CRES springs, with the pressure class set by the spring range and orifice size.

HOKE LR6000 Series Low-Pressure Relief Valves

Design Type: Right-angle, zero-friction poppet, encapsulated seat seal.

Orifice Size: 0.188 inch (4.78 mm).
Cracking Pressure: 5 to 550 psig (0 to 38 bar).
Maximum Operating Pressure: 5 to 700 psig (0 to 48 bar).
Proof Pressure: 1,050 psig (72 bar).
Burst Pressure: Over 2,800 psig (193 bar).
Reseat Pressure: 85% minimum of cracking pressure above 10 psig; 70% of cracking pressure below 10 psig.
Seal Material Options: Neoprene, Viton, Buna-N, Ethylene Propylene, Kalrez, Silicone.
Spring Code Ranges: 6 ranges from A (5 to 25 psig) through F (351 to 550 psig).
Other Features: Raised seal lip on poppet minimises seat contact, caps and bonnets pre-drilled for lockwire. Back pressure affects the cracking pressure on the low-pressure version.

HOKE Relief Valves: Sourcing and Technical Questions

The cracking pressure range of HOKE R6000 relief valves runs from 5 psig to 6,000 psig (0 to 414 bar) across four models: LR6000 at 5 to 550 psig, MR6000 at 150 to 2,500 psig, HR6000 at 150 to 5,000 psig, and XR6000 at 5,000 to 6,000 psig.

The maximum operating pressure is up to 7,000 psig (482 bar) on the HR6000 and XR6000, 6,000 psig (414 bar) on the MR6000, and 700 psig (48 bar) on the LR6000.

The difference is the pressure class, the orifice size, and the poppet design. The LR6000 uses a zero-friction poppet with a 0.188-inch orifice for 5 to 550 psig duty, the MR6000 uses a balanced poppet with a 0.188-inch orifice for 150 to 2,500 psig, the HR6000 uses a 0.094-inch orifice for 150 to 5,000 psig, and the XR6000 uses a 0.082-inch orifice for 5,000 to 6,000 psig.

We supply the R6000 in 1/4 inch male NPT × female NPT, 1/4 inch male NPT × GYROLOK, 1/4 inch GYROLOK × GYROLOK, 1/4 inch BSPT male × BSPT female, and 6 mm, 8 mm, and 12 mm GYROLOK pairings.

Yes, PED 97/23/EC certification and CE 0035 marking are standard on every R6000 model. For PED applications, use the valve in clean gas service only, free from dust and contamination (gas groups 1 and 2).
