DIN GG25 Bellow Globe Valve Description:
1. Design Standard: EN 13709, DIN3357
2. Face to Face: DIN3202 EN558-1
3. Flange ends: DIN2543-2545 EN1902-1
4. Test&Inspection: DIN3230 EN12266
5. Flexible graphite packing for dependable sealing performance.
6. Stem nut uses aluminum bronze material. Large valve is provided with thrust bearing to make it opened easily & flexibly.
7. Two piece design of packing gland to avoid stem clogging caused by squishing.
8. With sealing design, it is more safe and convenient to replace packing( Seat seal material could be decided by customer's request or according to valve's medium & temp. condition).
9. Operation: Hand wheel, Gear,Pneumatic actuator & Electric Actuator.
DIN GG25 Bellow Globe Valve Applications:
Bellow globe valve is used industrial and Oil/Gas piping applications requiring the higher flow capacity and lower pressure drop of full port internal flow-ways, and those applications where ease of repairability is desired.

FAQ
Q1: We are interested in your products?
A1: In order to recommend you suitable products, please provide detail information, like size, material, pressure, model.
Q2: Is the requirement for MOQ?
A2: For some small size, like 2''-48''(DN50-DN1200), it request the MOQ is 50pcs for each size. Generally speaking, it depends on your order.
Q3: How about the warranty?
A3: The warranty time is 18 months after leaving our factory. We can repair or change because of the quality problems.
Q4: Payment
A4: Mainly T/T, Western Union & PayPal are applicable for us. Payment Term: 30% prepayment, 70% balance paid before shipping or against copy of BL.
Q5: Can you manufacture different standards valves according to customer requirements?
A5: Yes. We can manufacture API,DIN,GOST,JIS standards for different pressure & temperature & size according to different needs.
If you want to know more about our products, please contact freely. We will patiently answer your all questions.
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.
