Priminox Overseas is an authorised distributor and stockist of HOKE Bleed Valves in India, and an ISO 9001 and ISO 14001 certified supplier based in Mumbai. HOKE bleed valves vent trapped pressure and purge liquids or gases from instrument manifolds, gauge assemblies and pressure measurement take-off lines. As part of HOKE's flow and fluid control components, they are installed in fluid-handling systems to safely release small amounts of pressure or fluid from the line. We stock the 6600 Series in five configurations: 6610 Straight, 6631 Directed, 6680 Tee, 6660 Elbow and 6670 Union, with 316 stainless steel bodies and maximum ratings up to 6,000 psig (414 bar) at 70°F (21°C).
The 6600 Series covers five configurations sharing a 316 stainless steel body and a 40 in·lb average operating torque (excluding the 6631). The 6610 and 6631 carry NPT inlets while the 6680, 6660, and 6670 use Gyrolok tube fittings.

A HOKE 6600 Series Bleed Valve is used for venting trapped pressure and purging liquids or gases from instrument manifolds, gauge valves, and pressure take-off lines. The valve releases media in a controlled way before instrument removal or system shutdown.
The difference is that the 6610 is a straight NPT bleed, the 6631 is a directed bleed with a 0.125" orifice built for gauge valves, the 6680 is a Tee Gyrolok configuration, the 6660 is an Elbow Gyrolok, and the 6670 is a Union Gyrolok. The NPT models suit threaded process ports; the Gyrolok models suit tube line installations.
The maximum operating pressure of HOKE 6600 Series Bleed Valves is 6,000 psig (414 bar) at 70°F (21°C) for the 6610, 6660, 6670, and 6680. The 6631 Directed Bleed Valve is rated to 5,000 psig (345 bar) at 70°F (21°C).
The 6600 Series is made from 316 stainless steel across all five configurations (6610, 6631, 6680, 6660, and 6670).
Priminox Overseas can supply NPT inlets in 1/8", 1/4", 3/8", and 1/2" on the 6610 (and 1/4" and 1/2" on the 6631), and Gyrolok tube ends in 1/4", 3/8", and 1/2" on the 6680 and 6670 (the 6660 is offered in 1/4" Gyrolok only).
The orifice size of the 6631 Directed Bleed Valve is 0.125 inch (3.20 mm), fixed across both the 6631H4Y and 6631H84Y part numbers.
The average operating torque is 40 in·lb across the 6610, 6660, 6670, and 6680.
Beyond instrumentation valves, Priminox stocks the complete HOKE product family — fittings, actuators, quick couplings and sampling solutions.
