Description

Within industrial process control and fluid conveyance sectors, the 75mm ball valve (DN80 / NPS 3 inch nominal diameter) acts as a core isolation and control component for medium-bore pipelines. Adopting quarter-turn operation architecture, it can switch between fully open and fully closed states within a split second. Unlike gate valves and globe valves which require multiple rotations for complete actuation, it gains remarkable superiority in emergency cut-off performance and daily operating efficiency. For engineering designers, confirming NPS 3 ball valve dimensions serves as a prerequisite step to implement proper installation inside confined spaces and avoid physical collision with pipe supports or adjacent mechanical equipment.
Our DN80 flanged ball valve is engineered and manufactured strictly per ANSI Class 150 / PN16 pressure standards, delivering zero-leakage sealing performance within its rated pressure and temperature scope. Customers may select WCB carbon steel valve bodies for water, oil, gas and general industrial service, or CF8M stainless steel bodies for mildly corrosive fluid and sanitary working environments.
Precision lapping is applied to sealing surfaces of balls and valve seats, paired with low torque operation design. This combination not only cuts actuator selection costs but also greatly extends the service life of valves working under frequent cycling conditions.
When analyzing 75mm ball valve price, apart from direct procurement expenditure, we advise purchasers to take hidden safety values such as fire-safe design and anti-static device into comprehensive consideration. These safety features are critical in petrochemical and natural gas sites with explosion risks, effectively preventing catastrophic accidents triggered by accidental fire outbreaks or static electricity accumulation. Every NPS 3 flanged ball valve manufactured by CHCV is fabricated in strict accordance with API 6D / ISO 17292 international standards. Fire safety test certificates complying with API 607 / ISO 10497 issued by authoritative third-party labs can be provided upon client requests.
We fully recognize that engineering projects impose stringent requirements on supply chain stability. All our valves undergo shell strength and sealing tests following API 598 specifications before delivery. Complete material traceability documents and NACE MR0175 / ISO 15156 compliance certificates are supplied to guarantee safe operation in sour service environments. For automated working scenarios, the valve can be fitted with an ISO 5211 standard mounting pad to mount pneumatic or electric actuators directly, enabling remote automatic control.

 Applications

  1. Oil & Gas Gathering System: Function as isolation valves on branch pipelines of main lines and metering skids, isolating inlets and outlets of pressure vessels such as separators and heat exchangers.
  2. Chemical & Fine Chemical Industries: Deployed for transporting moderately corrosive or high-purity chemical fluids; metal hard-sealed variants can handle high-temperature media or fluid containing solid particles.
  3. Municipal Water Supply & Sewage Treatment: Installed on inlet and outlet pipelines of medium-sized water pools as reliable isolation valves for maintenance shutdown.
  4. HVAC & District Energy Supply: Mounted at inlet and outlet ports of chilled water and hot water units to achieve precise fluid shut-off and flow distribution.

FAQ for Global Purchasers

Q1: What core factors govern 75mm ball valve price? Is customized production available to match project requirements?
A1: Four key elements cause price fluctuations:
  1. Body material, stainless steel variants cost far more than carbon steel versions;
  2. Pressure rating, Class 300 specifications are priced higher than Class 150 types;
  3. Seat & sealing material: PTFE suits ambient temperature service, PPL adapts to high-temperature environments, while metal sealing applies to abrasive working conditions;
  4. Actuation type, manual valves have the lowest cost, whereas pneumatic and electric actuators differ greatly in pricing.

We support full customization based on project demands, and can deliver accurate quotations and model selection confirmation after receiving your valve data sheet.

Q2: How to verify whether the supplied NPS 3 flanged ball valve satisfies API 607 fire safety standards?
A2: Our standard valves adopt valve bodies manufactured per ASTM A216/A351 standards, with fire-safe structured seats and sealing rings. For projects with strict requirements, we can offer API 607 / ISO 10497 fire safety test reports released by recognized third-party institutions including BV, SGS and Lloyd’s. Each valve is delivered with detailed quality guarantee papers and inspection reports, realizing full-process quality traceability covering raw material incoming inspection to finished product delivery. For key projects, on-site factory supervision and witnessed testing services are also available as requested.
