Q11F001 Female Thread Brass Ball Valve

Q11F001 is a female thread brass ball valve designed for on-off service in low-pressure water, gas, and heating lines. It features a quarter-turn operation and a full-bore ball that allows unrestricted flow when open. The female thread connection enables direct pipe threading without additional fittings, reducing assembly steps and potential leak points in compact installations.

Key Benefits

What This Model Gives You

  • Female thread connection allows direct pipe threading, eliminating the need for extra fittings
  • Quarter-turn operation provides fast and reliable on-off control with visual position confirmation
  • Full-bore ball design maintains full flow capacity with minimal pressure drop
  • Brass body resists corrosion in water and low-pressure gas systems
  • Compact size fits in tight spaces where larger valves would not install
  • Part of a brass valve programme certified to ISO 9001 and ISO 14001
Problems Solved

Problems It Removes

  • Existing systems with male thread valves require adapters; female thread valves eliminate this need
  • Longer valves with flanged or welded ends take up too much space in tight enclosures
  • Corrosion in steel valves leads to leaks in water and gas lines; brass resists this better
  • Slow multi-turn valves are hard to operate in frequent-use applications; quarter-turn ball valves are faster
  • Buyers need a single supplier for both small and large valves across multiple families
Application Scenarios

Where It Is Installed

  • Isolation of branch lines in residential and commercial water supply systems
  • Control of low-pressure gas lines in HVAC and heating equipment
  • Service valve installation in compact mechanical enclosures or pump skids
  • Replacement of obsolete brass ball valves in existing piping with matching thread size
  • Use in low-pressure steam or hot water circuits where corrosion resistance is required
Who It Is For

Buyers It Suits

  • Plumbing contractors sourcing brass valves for residential and commercial water systems
  • HVAC and heating system installers needing compact isolation valves
  • Equipment builders integrating valves into machinery with limited space
  • Maintenance teams replacing valves in existing systems with standard female thread connections
  • Distributors stocking a range of brass ball valves from DN10 upward
Technical Features

How It Is Built

  • Quarter-turn operation for fast on-off control
  • Female thread connection for direct pipe threading
  • Full-bore ball design for unobstructed flow when open
  • Brass body with internal ball and stem construction
  • Part of a brass valve range covering DN10 to DN2600
  • Designed for low-pressure service up to 4.0 MPa
Materials

Material Selection

  • Body, ball, and stem are made from brass; material composition confirmed per order
  • Seat material is selected based on the medium and temperature of the application
  • Material certificates are issued with the order when requested
Manufacturing

How It Is Made

  • Brass casting inspected and machined on in-house fine machining equipment
  • Ball and stem machined and assembled as a matched unit
  • Seat fitted and the ball set for free rotation and tight closure
  • Assembled valve cycled and pressure tested before packing
  • Marked, wrapped, and crated for container shipment from Tianjin
Quality Control

How It Is Checked

  • Dimensional check of thread size and body length before assembly
  • Seat and shell tightness tested on the assembled valve
  • Operating torque and full quarter-turn travel verified on every unit
  • Testing carried out on the 10 sets of imported inspection and testing equipment
  • Records maintained under the ISO 9001 quality management system
Certification

Certificates Issued With This Valve

  • ISO 9001 quality management system certification
  • ISO 14001 environmental management system certification

Certification statements are limited to the management system certificates the factory actually holds. Product-level approvals for your market are confirmed before order.

Customisation

What Can Be Changed

  • Thread size and length confirmed per order based on the buyer's piping standard
  • Seat material selected for the medium and temperature on the buyer's line
  • Lever or actuator option available for remote or automated operation
  • Private label marking and packing on OEM orders
  • Mixed-diameter orders combined with other valves in one container
Comparison

How It Compares With the Alternatives

Male thread brass ball valveThe male thread version requires a female fitting; the female thread connects directly to a male pipe thread
Flanged brass ball valveThe flanged version needs two flanges and bolts; the female thread version installs directly without extra fittings
Brass gate valveThe gate valve is multi-turn and slower; the ball valve offers faster operation and a more compact profile
Plastic threaded ball valvePlastic valves are lighter but less durable under pressure and temperature; brass offers better mechanical strength and longevity
Use Guide

Installing and Operating This Valve

  • Confirm the pipe thread standard (e.g. G, NPT) and size before ordering
  • Apply thread sealant or tape to the male pipe thread before inserting into the valve
  • Hand-tighten the connection first, then use a wrench for final tightening to avoid over-torquing
  • Do not use the valve as a throttling device; it is designed for on-off service only
  • Cycle the valve periodically on lines that remain in one position for long periods
  • Inspect the connection for leaks after initial operation and after pressure testing
FAQ

Q11F001 Female Thread Brass Ball Valve FAQ

What size and pressure rating is Q11F001?

The nominal diameter and pressure rating are confirmed on request based on the buyer's piping standard and service conditions.

Can this valve be used for gas service?

Yes, it is suitable for low-pressure gas lines when the material and seat are confirmed for the specific gas type and temperature.

Which thread standard does it use?

The thread standard is confirmed per order based on the buyer's piping system, such as G (metric) or NPT (American).

Is the ball valve suitable for throttling?

No. It is designed for on-off service only. Throttling may damage the seat and reduce sealing performance.

Can it be supplied with a lever or actuator?

Yes. The stem can be fitted with a lever, gearbox, or pneumatic/electric actuator before shipment.

Do you supply larger diameters in the same series?

Yes. The Q11F brass ball valve series continues through the nominal diameter range from DN10 to DN2600.

What certification does the factory hold?

Tianjin MIC Valve Co., Ltd. is certified to the ISO 9001 quality management system and the ISO 14001 environmental management system.
