Description
Within industrial piping networks, the 40mm brass ball valve serves as an ideal shut‑off and control component for DN32 pipelines. While buyers inquire about 40mm brass ball valve price, both build quality and service life rank among their core concerns. Our full port construction eliminates bore reduction, delivering smooth medium flow and minimal pressure drop. It delivers dependable zero‑leakage shut‑off performance across water treatment, compressed‑air loops, low‑pressure steam and oil transfer applications. Compatible with both metric and imperial piping standards via BSPP / NPT threaded ends, it simplifies field assembly for international engineering projects.
Material Grades & Manufacturing Standards
‑ Body / End Cap: CW617N European‑spec forged brass with dezincification‑resistant and stress‑corrosion‑resistant properties. Optimized wall thickness grants higher pressure endurance versus conventional cast brass. ‑ Ball: Hard‑chrome‑plated brass ball (surface hardness ≥900 HV) with polished surface finish Ra≤0.4 μm, featuring low actuation torque and superior wear resistance. ‑ Seat & Sealing Components: 25 % glass‑fiber‑reinforced PTFE combining anti‑cold‑flow performance and low‑friction characteristics, achieving ISO 5208 Rate A zero‑leakage sealing. ‑ Stem: anti‑blowout structure fitted with dual O‑ring seals to guarantee safe operation under pressurized conditions.
Every individual valve undergoes a 1.5‑times shell hydrostatic pressure test as well as a 1.1‑times low‑pressure air tightness test. Available certifications cover EN 13828, NSF/ANSI 61 for potable‑water service and PED 2014/68/EU Pressure Equipment Directive.

Typical Applications
‑ Industrial cooling circulation systems: sectional isolation for heat exchanger and cooling tower inlet and outlet points for straightforward maintenance.
‑ Compressed‑air piping networks: branch shut‑off valve suitable for dry or lightly‑lubricated compressed‑air service.
‑ Natural‑gas pressure regulating stations and branch pipelines: satisfies Rate‑A gas‑valve leakage requirements; fire‑safe variants are optional.
‑ HVAC systems: control for chilled‑water and hot‑water coils with stable pressure‑withstand and temperature‑resistant capabilities.
‑ Auxiliary piping for food‑beverage and pharmaceutical facilities: lead‑free brass material available to satisfy potable‑water and sanitary requirements.
Why Select Our 40mm Brass Ball Valve
When comparing brass ball valve 40mm price against adjacent sizes such as 32mm brass ball valve price and 50mm brass ball valve price, our 40‑mm model strikes an optimal balance between flow capacity and overall expenditure. Its full port design yields a Cv value of 37, greatly outperforming reduced‑bore counterparts of the same nominal size, yet its cost is only moderately higher than the 32‑mm variant, making it a cost‑effective option for high‑flow scenarios.
‑ Precise sizing: DN32 (40 mm) dimension fits metric piping perfectly; full port layout delivers Cv up to 37 and minimizes system pressure loss. ‑ Wide‑ranging certifications: potable‑water NSF, gas‑service approvals and PED pressure‑equipment compliance support export to European and North‑American markets. ‑ Robust mechanical layout: 2‑piece forged‑brass body allows internal component replacement without dismantling full pipeline sections during servicing. ‑ Ready‑to‑ship inventory: standard BSPP configurations kept in stock; custom options include modified handle colours, extended stems and mounting interfaces for electric / pneumatic actuators.
FAQ
Q1: Are 40 mm brass ball valves interchangeable with 1½‑inch ball valves? What installation precautions should be taken?
A: The 40 mm metric nominal size corresponds to DN32, functionally equivalent to imperial 1¼‑inch (DN32), yet it differs from 1½‑inch (DN40) and cannot be directly swapped. Prior to fitting, verify pipe outer diameter and thread standards; note BSPP and NPT threads are not cross‑compatible. Adaptors or custom‑end configurations are available upon request; confirm piping specifications before placing orders.
Q2: Can this valve operate within hot‑water circuits? What is its maximum temperature rating?
A: Standard PTFE seats suit hot‑water service ranging from ‑20℃ to 120℃. For steam or high‑temperature hot‑oil service up to 180℃, select upgraded PEEK‑reinforced valve seats alongside high‑temperature graphite packing.
