GOST Globe Valves

GOST Globe Valves of Hanno Valve is manufacture according to GOST 5762, face to face dimension is according to GOST 3706, end flange dimension is according to GOST 33259. GOST Check Valves can make for flange connection end or butt welded connection end. GOST Globe Valves mainly have manual, electric, pneumatic and bevel gear.

The axis of the stem in theGOST Globe Valves align perpendicularly to the sealing surface of the valve seat. With a relatively short opening or closing stroke, the J41W globe valve offers a reliable shut-off action, making it ideal for medium control in cutoff, adjustment, and throttling applications. Once the J41W series stainless steel globe valve is fully open, its seat and disc sealing surfaces no longer contact, minimizing mechanical wear on the sealing surface. Globe valve seats and flaps are relatively easy to access and service, allowing for sealing element maintenance or replacement without removing the entire valve from the pipeline—especially useful when the valve and pipeline are welded. Due to the flow direction change in such valves, the flow resistance of a globe valve is typically higher than that of other types.

Structural Characteristics of theGOST Globe Valves:

1. Enhanced Structure and Performance: It features a robust design, reliable sealing, excellent performance, and an aesthetically pleasing appearance. The rigidity of the valve stem is reinforced, significantly reducing noise and vibration while improving service life and overall performance.

2. Flexible Installation: The shut-off valve can be installed in any pipeline position, with media flowing from bottom to top.

3. Advanced Sealing and Improved Torque: For sizes above DN250, it incorporates a multi-seal design and double-bracket support with guided motion, greatly enhancing resistance to water hammer. The media entry from above addresses high opening and closing torques in large-diameter valves, ensuring a tighter seal and preventing leakage in the stuffing chamber. The "close" torque is reduced to 10% of standard valves, while the "open" torque is only 3%.

4. Corrosion Resistance: The stainless steel construction offers excellent corrosion resistance, suitable for pipelines carrying various corrosive media.

5. High-Temperature Durability: The alloy steel version of the globe valve is ideal for high-temperature steam and oil pipelines, with notable resistance to extreme temperatures.

Customer Requirements:

1. For any specific customer requirements, the following details must be specified in the purchase order:

● Structural length

● Connection type

● Nominal diameter, full/reduced diameter, pipe size

● Operating medium, temperature, and pressure range

● Test procedures, inspection standards, and other special requirements

2. ERA valves can accommodate various drive configurations based on customer needs.

3. If the customer provides a specific valve model, they must clearly explain the model's specifications and requirements, and both parties must agree on these terms in the contract.

4. For advance orders, customers should contact us with the required valve model, specifications, quantity, delivery schedule, and location. A 30% deposit or full payment is required, with the balance due prior to shipping, to ensure timely shipment arrangements.
