Core Applications
Hydraulic Fracturing: Maintains precise backpressure; erosion-resistant trim prevents internal washout from high-velocity frac sand.
Drilling & Mud Systems: Integrated into choke manifolds for kick control and wellbore stability.
Well Testing & Flowback: Ensures accurate flow management during formation testing and cleanup.
High-Pressure Pipelines: Deployed in gathering stations requiring strict pressure drops and zero ambient leakage.

Frequently Asked Questions
Q: Does your High Pressure Throttle Valve fully comply with API 6A and NACE MR0175?
A: Yes. Every valve holds an official API 6A product monogram. For sour gas (H₂S) service, we utilize NACE MR0175-compliant materials to prevent sulfide stress cracking.
Q: Can you provide third-party inspection (TPI) reports prior to shipment?
A: Absolutely. We routinely work with SGS, Bureau Veritas (BV), Intertek, and DNV for material testing verification, hydrostatic test witnessing, and dimensional checks.
Q: What is your typical manufacturing lead time for bulk orders?
A: Standard API 6A flanged or union-ended configurations take 30 to 45 days. Large-volume custom projects with specialized actuators require 60 to 75 days.
Q: Do you support OEM / Private Label manufacturing?
A: Yes. We provide full OEM manufacturing for international distributors and oilfield brands, complete with custom nameplates and color schemes under strict NDA.
Q: What materials do you use for the valve trim?
A: To combat severe erosion from frac sand, our stems, needles, and seats are manufactured using Solid Tungsten Carbide (WC) or high-grade stellite cobalt base alloys.
Q: Are Mill Test Certificates (MTRs) and technical documents provided?
A: Yes. Every shipment includes a comprehensive package: EN 10204 3.1 MTRs, hydrostatic test charts, NDT reports, and O&M manuals in English.
Q: What is your Minimum Order Quantity (MOQ)?
A: For standard configurations, our MOQ starts at 1 to 5 units to allow distributors to run local market trials. Tiered volume discounts apply to container-load orders.
Q: How do you package these valves for international freight?
A: Valves are treated with anti-rust oil, fitted with plastic flange protectors, wrapped in vapor-barrier plastic, and secured inside ISPM-15 compliant, fumigated wooden crates.
Q: What warranty terms do you provide?
A: We offer a 12-month operational warranty from the date of field commissioning, or 18 months from the bill of lading date, whichever comes first.
