Main Features
Pressure Seal Design: The bonnet adopts a pressure seal structure. As the system pressure increases, the sealing performance is correspondingly enhanced, effectively preventing medium leakage, which is particularly suitable for high-pressure environments.
Welded Butt-Weld Connection: The butt-weld end (BW) connection method enables the valve to closely integrate with the pipeline system, enhancing the integrity and tightness of the system. It also reduces the risk of leakage at the connection and improves the reliability of the system.
Carbon Steel WCB Material: The valve body is made of carbon steel WCB, which has good mechanical properties and corrosion resistance. It can maintain stable operation within a wide range of temperatures and pressures, with relatively low cost and high cost performance.
Flexible Wedge Structure: Equipped with a flexible wedge gate, it can automatically adjust the fit between the sealing surface and the valve seat, ensuring good sealing performance during valve opening and closing. At the same time, it reduces operating torque and extends the service life of the valve.
Non-Rising Stem: The non-rising stem design ensures that the stem does not rise during operation, saving space and facilitating installation and maintenance. It also avoids the risk of medium leakage caused by stem rising.
Multiple Operation Methods: It can be equipped with a manual gear operating mechanism, which is easy to operate. Suitable operation methods can be selected according to actual working conditions to meet the needs of different users.

Application Fields
This gate valve is suitable for high-pressure fluid transmission pipeline systems in industries such as petroleum, chemical engineering, natural gas, and electric power. It is especially applicable to occasions requiring high sealing performance and reliability, such as petroleum refining equipment, natural gas transmission pipelines, and chemical reaction systems. Its excellent performance and wide applicability make it an ideal choice in the field of industrial fluid control.
Quality and Testing
Manufacturing Quality: Strictly manufactured in accordance with API 600 and relevant international standards to ensure product quality and performance.
Testing Standards: Rigorous testing is conducted in accordance with API 598 standards, including shell strength testing and tightness testing, to ensure that each valve meets high-quality standards before leaving the factory.
API 598 test durations by size, why the timer starts after the pressure settles, and what a 1.5 times shell test cannot tell you about service.
Pneumatic actuator failure modes and field diagnostics: air supply quality, diaphragm rupture, spring relaxation, torque margins and partial stroke testing.
How a butterfly valve disc is fixed to its stem: taper pins, pinless hubs and through shafts, the backlash each allows, and the failures they cause.
Steam PRV station design: critical pressure ratio, Kv sizing, 1/3-2/3 parallel turndown, series stations and safety valve sizing rules.
Why LNG ball valve seats that pass warm tests leak cold at -162°C: contraction arithmetic, cold preload, PCTFE vs PTFE, ISO 28921-2 and MSS SP-134 limits.
What API 607 proves: burn sequence, 7th-edition leak limits per NPS, cavity pressure rules, API 6FA vs ISO 10497, and the clauses buyers must check.
MSS SP-80 bronze valves: the class number is a saturated steam rating, not a pressure rating. Alloys, threads, lead-free rules and where bronze stops.
Stellite or tungsten carbide for erosive service: erosion angles, hardness ratios, HVOF vs weld overlay, the 500 C limit, and the clauses that win acceptance.
Valve coating is a defect-budget decision, not a product choice: ENP vs FBE vs sprayed aluminium, holiday arithmetic, CUI and the specs that win acceptance.
Temporary and start-up strainers for commissioning: placement, plate versus mesh, blowdown discipline and the removal record that proves it was pulled.
What MSS SP-25 marking really commits to: body symbols, three-symbol trim marking, melt identification and the certificate that closes the loop.
Why ball valves pass high-pressure seat tests and fail at 0.6 MPa: seat preload arithmetic, SPE and DPE seats, DBB vs DIB-1/DIB-2, and test-proofing specs.
RF, RTJ and butt-weld valve ends compared: how each joint seals, which duty suits it, and the four assembly errors that cause most joint leaks.
Why PTFE and PFA liners fail when the chemistry is right: permeation arithmetic, vacuum collapse, cold flow and the 11:1 expansion mismatch at the flange.
C95800 and C95500 are cast to ASTM B148; C63200 is wrought to ASTM B150. Aluminum and manganese levels decide strength, weldability and valve use.
Jacket heat load arithmetic, sulfur's 159 C viscosity trap, the separate jacket pressure test and the weld failures buyers discover in year five.
API 603 and API 600 both cover bolted bonnet gate valves, but wall thickness basis, class ceiling and casting rules decide which one you can actually buy.
ISO 5208 Rates A-G explained with real numbers, how API 598, API 6D and FCI 70-2 map across, and what metal seats can honestly achieve.
How to choose a forged or cast valve body: API 600 vs API 602 size limits, casting quality factor, NDT coverage, weld repair policy and cost crossovers.
How pressure seal bonnet valves work, why bolted bonnets stop at Class 900, seal ring materials, disassembly rules and the low-pressure leak signature.
