Final material grade, heat treatment, size, class, temperature limit, applicable standard, inspection and documentation must be confirmed for the exact model in the approved datasheet and order specification.
Frequently Asked Questions
Confirmed body materials on this page are WCB, WC6, WC9 and ZG20CrMoV. F91 requirements can be reviewed against the project specification before configuration is confirmed.
The published operating range for this Power Station Gate Valve is -29℃ to 575℃. The exact limit for a WC6 gate valve or WC9 gate valve depends on pressure, design data, component materials and the governing specification.
Yes. Vornet can review material, connection, sealing, operation and documentation requirements before confirming a custom valve solution.
The current product is specified to NB/T 47044 and ASME B16.34. Any additional standard must be identified in the inquiry and verified during engineering review.
The documentation package is agreed during order review and may include material certificates, pressure test reports and inspection records. Required ITP, MTC or third-party inspection scope should be stated with the inquiry.
Product Overview
Vornet WC6 WC9 High Temperature Power Station Gate Valve is engineered for isolation services in thermal power plants, steam systems and high pressure applications. The valve is designed to provide reliable sealing performance under high temperature and high pressure working conditions.
The valve body is made of high quality alloy steel WC6 and WC9, which offers excellent high temperature strength and oxidation resistance. The wedge is precision machined and heat treated to ensure long service life and reliable sealing.
The offered configuration can be reviewed and manufactured to the agreed edition of NB/T 47044, ASME B16.34 or another project-specified design basis when included in the approved quotation and datasheet. Pressure testing, inspection, acceptance criteria and records are confirmed in the approved ITP, quotation and purchase specification for each order.
- High Temperature Performance: Operating temperature range from -29°C to 575°C, subject to material grade, pressure class and project conditions.
- High Pressure Capability: Pressure rating from Class 900 to Class 2500 (PN200–PN320).
- Reliable Sealing: The sealing arrangement is selected for the stated shut-off duty; acceptance criteria and expected service life depend on the actual medium, pressure, temperature, cycling and maintenance conditions.
- Custom Solutions: Materials, trims, connection types and actuators available per project requirements.
Procurement Considerations for Middle East and South Asia Projects
Saudi Arabia and UAE enquiries may involve utility or captive-power systems serving refinery, petrochemical and industrial projects. State the exact line duty—main steam, feedwater, boiler isolation or auxiliary service—together with pressure class, temperature, material, butt-weld details, actuation, cycling and shutdown requirements. NACE MR0175/ISO 15156 should be specified only where actual sour-service exposure and project documents require it.
Indian power and process-plant EPC packages should identify the approved design basis, piping class, WC6/WC9 or other specified material, pressure-temperature rating, heat treatment, welding/NDE, pressure testing, ITP and document register. IBR should be included only when the actual project requires it. Optional inspection, third-party witnessing and documentation remain subject to project requirements and must be confirmed in the approved quotation and datasheet.
