Product Overview
CAMTOP Weco Пробка Клапаны deliver exceptional performance in high-pressure well service applications. Engineered for the most demanding oilfield environments, our ULT series plug valves handle pressures up to 20,000 PSI and are available in sizes from 1″ to 4″ with Weco hammer union end connections. The proprietary two-piece floating plug/stem design (3″ and larger) and dual-seal segment configuration provide superior sealability, extended body life, and resistance to erosive fluids including sand, proppant, and cement. Both Стандарт and Sour Газ (H₂S) service configurations are available, with low-temperature (–40°C) options for arctic environments.

Шпонка Features
- Two-piece floating plug/stem design: Proprietary floating plug and stem uniformly distribute load against the downstream seat to improve sealability and reduce plug wear (3″ and larger models).
- Fast, simple field repair: Bottom entry design provides access to all valve internals without having to remove the operator or actuator, minimizing downtime.
- Eliminates body washout, extends body life: Dual seals direct flow between the seal segment and plug to provide long, trouble-free service life.
- Handles sand, proppant, and cement: Linear wave springs prevent small particles from entering the metal-to-metal seal area, enabling use in a broad range of abrasive applications.
- Взаимозаменяемый design: Internal components of 1″ size interchange with Weco DR valve components, potentially extending the life of existing valve bodies.
- Eliminates corrosion in segment sealing area: Dual segment seals greatly reduce erosive fluid flow between the seal segments and the plug valve body to improve sealing capabilities and extend service life.
- Fast assembly: Цельный stem and plug provide fast, sure assembly without adjustments (below 3″ models).
- High pressure capability: Up to 20,000 PSI cold working pressure (CWP) for demanding high-pressure well service.
- Стандарт and Sour Газ service: Available in both Стандарт and H₂S (Sour) service configurations to meet API requirements.
- Low temperature option: Low-temperature (–40°C) equipment available for arctic and cold-climate operations.

Frequently Asked Questions (FAQ)
Q: What is the maximum working pressure of CAMTOP Weco Пробка Клапаны?
A: CAMTOP Weco Пробка Клапаны are rated up to 20,000 PSI cold working pressure (CWP). Specific models such as ULT 200 and select handwheel configurations are rated at 20,000 PSI, while most standard models are rated at 15,000 PSI. Sour service models are typically rated at 10,000 PSI.
Q: What sizes are available?
A: The ULT series is available in nominal sizes from 1″ to 4″, including 1×2″ crossover sizes. Each size is offered in multiple pressure ratings and service configurations.
Q: What end connections are offered?
A: Стандарт Weco hammer union end connections include 1502, 2202, 1002, and 1505. Other end connections are available upon request; please consult the factory for custom configurations.
Q: What services are supported — Стандарт or Sour Газ?
A: Both Стандарт and Sour Газ (H₂S) service configurations are available. Sour service models use NACE MR-01-75 compliant materials and are typically rated at 10,000 PSI. Please specify your service requirements when ordering.
Q: Is low-temperature service available?
A: Yes. Low-temperature (LT) versions rated for –40°C are available. These are designated with the P/N-LT part number suffix and use materials qualified for cryogenic impact performance.
Q: What is the recommended service fluid for these plug valves?
A: The recommended service fluids include slick water, sand, proppant/gel, energized fluids (nitrogen and CO₂), inhibited acids, and cement. The dual-seal segment and linear wave spring design specifically addresses abrasive and corrosive media.
Q: What operating methods are available?
A: Three operating methods are available: Ручной (lever operated), Handwheel (for larger sizes and higher torque), and Гидравлический Actuator (for remote or automated operation). 1″, 1×2″, ULT 150, DR 150, and DR 200 models can be furnished with hydraulic actuators.
Q: How does the floating plug design improve sealability?
A: The proprietary two-piece floating plug and stem (3″ and larger) uniformly distributes the sealing load against the downstream seat. This improves sealability, reduces localized plug wear, and extends service life compared to fixed plug designs.
Q: What makes field repair fast and simple?
A: The bottom entry design provides direct access to all valve internals — plug, stem, seal segments, and springs — without having to remove the operator or actuator. This minimizes downtime and eliminates the need for specialized tools.
Q: What is the warranty period?
A: CAMTOP Weco Пробка Клапаны are backed by a 12-month warranty from the date of shipment against defects in materials and workmanship. Extended warranty options are available for bulk and long-term supply agreements.
