Shanghai Zhibang Valve Manufacture Co., Ltd. has been a specialized manufacturer of industrial valves since 2016. Our JIS F7305 Pneumatic Globe Valve is engineered specifically for demanding offshore oil and gas environments, where reliability, corrosion resistance, and safety are paramount. Crafted from premium 316L stainless steel and equipped with an explosion-proof pneumatic actuator, this valve delivers precise flow control under high pressure and harsh conditions. With ISO9001 certification and a proven track record in global markets, we ensure that every valve meets rigorous quality standards.
Product Overview & Key Features
- Material Excellence: 316L stainless steel body and trim provide exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking – ideal for offshore seawater and hydrocarbon services.
- JIS F7305 Compliant: Designed and manufactured in accordance with Japanese Industrial Standard JIS F7305, ensuring compatibility with common offshore piping systems in Asia and beyond.
- Explosion-Proof Pneumatic Actuator: The actuator is certified for hazardous locations, offering reliable operation in explosive gas atmospheres typical of oil and gas platforms. Double-acting or spring-return configurations available.
- Leak-Free Performance: Precision-machined seat and disc ensure bubble-tight shut-off, meeting Class VI leakage requirements. Optional metal-to-metal or soft seating for different service needs.
- Compact & Durable: Lightweight yet robust design minimizes support structure requirements while withstanding vibration, thermal cycling, and external impact.
- Easy Maintenance: Accessible bonnet design allows for quick in-line servicing, reducing downtime during platform operations.

Frequently Asked Questions
Q1: Can this valve be used for high-pressure steam services in offshore applications?
A: The valve's 316L body and pressure rating of 16K (approximately 16 bar at 350°C) makes it suitable for saturated steam and low-pressure superheated steam. For higher steam parameters, please consult our engineering team for alternative materials or pressure classes.
Q2: What is the typical maintenance interval for the pneumatic actuator?
A: Under normal offshore conditions, the actuator should be inspected every 6 months for seal integrity and mechanical wear. Lubrication and filter replacement are recommended annually. Our user manual provides detailed maintenance schedules.
Q3: Do you provide actuator accessories like positioner, solenoid valve, or limit switches?
A: Yes, we offer complete automation packages including smart positioners (I/P), Namur solenoid valves, proximity switches, and air filter regulators. These can be supplied pre-mounted and tested.
Q4: Is the explosion-proof certification internationally recognized?
A: The actuator carries ATEX (IECEx) certification for Ex d IIB T4/T6 and IP67. Additional certifications (e.g., NEC Class I Div 1) can be provided upon request. Please note that specific certifications require order confirmation.
Q5: What is the minimum operating pressure for the actuator?
A: For pneumatic actuators, the minimum supply pressure is typically 4 bar. Double-acting actuators require continuous pressure; spring-return actuators will operate down to 3.5 bar but with reduced torque. Refer to our actuator data sheet for exact values.
Q6: Can the valve be supplied with NACE MR0175 compliance for sour gas?
A: 316L stainless steel is generally NACE compliant for H₂S environments up to certain limits. We can provide NACE MR0175/ISO 15156 documentation upon request. For severe sour service, consider our UNS N08904 or Alloy 625 trim options.
Q7: What is the standard delivery time for DN50 size valves?
A: For standard valves without special trim or actuator options, our lead time is 30-45 working days from Shanghai. Expedited delivery may be available for urgent orders – please inquire with our sales team.
Q8: Do you offer spare parts kits for the globe valve?
A: Yes, we provide complete service kits including seats, disc, stem packing, gaskets, and actuator seal kits. Parts are available for quick dispatch from our Shanghai warehouse to support global maintenance needs.
