API 6A Positive Choke Valve H2 | Fixed Orifice

Home › Flow Control & Choke Valves › API 6A Positive Choke Valve H2

Product Overview

The DEENPU positive choke valve, H2 type, meters flow through a fixed-diameter ceramic or tungsten carbide choke bean. It is the simplest and most reliable way to hold a set flow rate on well test, flowback and production manifolds, with no moving parts exposed to the flow.

Bodies are rated to 15000 PSI and use the same bonnet interface as our adjustable chokes — converting a positive choke into an adjustable choke (or back) is a bonnet-assembly swap. Beans from 1/64″ increments are supplied with a dedicated bean wrench for fast, safe changes.

Key Features

• Fixed orifice choke beans in ceramic or tungsten carbide
• Working pressure up to 15000 PSI
• Bonnet interchangeable with DEENPU adjustable choke bodies
• Bean sizes in 1/64″ increments, full size range
• Bean wrench and bean adapter supplied
• API / ANSI flanged or threaded end connections

Quality & Testing

Every DEENPU API 6A Positive Choke Valve H2 is manufactured under our API-compliant quality system: raw material traceability, 100% dimensional inspection, hydrostatic pressure testing and hardness verification before packing. Material certificates, inspection reports and API documentation are provided with shipment on request.

Applications

• Well testing and clean-up flowback lines
• Production wellhead choke (constant rate)
• Gas lift and injection rate limiting
• Frac flowback manifolds

Frequently Asked Questions

Q: What is the difference between a positive choke and an adjustable choke?

A: A positive choke uses a fixed-size bean to hold one flow rate; flow changes require changing the bean. An adjustable choke varies the orifice with a stem and seat, without shutting in the well.

Q: How do I select the bean size?

A: Provide expected flow rate, upstream pressure and fluid; DEENPU can help size the bean, or use standard well-test bean sizing charts. Beans in 1/64″ steps cover all common rates.

Q: Are beans interchangeable with other manufacturers’ chokes?

A: DEENPU beans follow industry-standard dimensional conventions; tell us your existing choke model and we will match or supply an adapter.
