PRODUCT FEATURES
2Pc F/F Ball Valve — Product Features
“A two-piece male manual ball valve that can be disassembled into two parts, offering threaded connection options, a variety of material choices, and PTFE seals. Please refer to the enclosed technical specifications for details.
Two-piece male valve body
A two-piece male-female ball valve designed for manual on/off operation in piping systems.
Manual Ball Valve Operation
Turning the handle rotates the valve stem and ball together, thereby opening or closing the flow path.
Threaded Connections
BSPT, BSPP, and NPT thread types are available; please confirm the required sizes and specifications.
Material and Seat Options
The parts list includes WCB / CF8 / CF8M / 2205 valve body materials and PTFE seat components.”””
OPERATING PRINCIPLE
How 2Pc F/F Ball Valve Works
“A gentle turn is all it takes to control fluid flow. Turning the handle causes the valve stem and the ball to rotate in unison.
-
1. Turn the handle
The manual handle transmits rotational motion to the valve stem.
-
2. Rotate the ball
The valve stem drives the ball, thereby changing the direction of the flow path.
-
3. Open or close
When the ball’s orifice aligns with the flow path, fluid flows through; when the ball is rotated to block the flow path, the valve closes.”

PURCHASING SUPPORT
Frequently Asked Questions
Find answers to common questions about sizing, materials, threaded connections and operating conditions.
What is 2PC double male thread ball valve?
It is a 2-piece floating ball valve with male thread on both ends. Designed to connect to female threaded fittings on both sides.
Pressure rating?
1000WOG (PN16), working pressure up to 16bar at room temperature.1000WOG（PN16）
Working temperature range?
PTFE seat: 0℃ ~ 120℃. If over 120℃, we can offer other seat material.
What media can it handle?
Water, compressed air, natural gas, oil, weak acid & alkali. Not for strong corrosive medium.
Is it full port or reduced port?
Standard 2PC ball valve is full port, low flow resistance.
Can it be used for steam?
For saturated steam, please advise temperature and pressure. PTFE seat is limited for high temp steam.
Do you do 100% pressure test?
Yes. Every valve will pass air leakage test before packing.
MOQ?
Small MOQ available. Mixed sizes in one order acceptable.
Packing method?
Each valve in plastic bag, then small box, carton outside. Wooden pallet optional.
Installation tips?
Do not over-tighten the male thread when connecting. Use thread seal tape properly. Avoid heavy impact on valve body.
Can I put my own logo /custom label?
Yes, OEM & ODM available. Logo on handle or body.
Is it bidirectional sealing?
Yes, floating ball design, bidirectional sealing.
Tips for installation?
Do not over-tighten the male thread when connecting. Use thread seal tape properly. Avoid heavy impact on valve body.
Can the valve be installed vertically or horizontally?
Both horizontal and vertical installation are okay. Handle can be adjusted position.
What’s the warranty?
12 months warranty against manufacturing defect. Not cover damage from wrong operation.
How to prevent leakage?
Do not over-tighten thread when installation; avoid impact. Regular inspection for long time service.
“What sizes are available?
The general product specifications list sizes from 1/2” to 2” (DN15–DN50). The accompanying size chart currently covers DN15–DN50; please verify the specific dimensions for the size you require.
What materials can I choose from?
The original bill of materials includes 201, CF8, and CF8M valve body options, as well as a variety of ball and internal component materials. Specific configuration combinations should be confirmed prior to ordering.
Are BSPT, BSPP, and NPT connections available?
Standard stock consists of BSPT; however, the original specifications list BSPT, BSPP, and NPT threads. Please provide the thread standard and nominal size when requesting a quote so that availability can be confirmed.
What are the temperature and pressure limits?
The accompanying general data indicates an operating pressure of 1.6 MPa and an operating temperature range of 0°C to 120°C. Suitability of this product for specific fluids and temperatures must be confirmed separately.
Can this valve be used for throttling?
The accompanying operating instructions recommend against leaving the valve in a partially open position for extended periods, as high-velocity fluid may erode the PTFE seat.
What is the lead time for orders?
We maintain a stock of 5,000 BSPT valves for standard orders; other thread types require customization, with a production capacity of 50,000 units within 15 days.
What is the product quality like? Is there a warranty period?
Every valve undergoes rigorous quality inspection, including testing of the material, threads, seals, and valve body, and is backed by a one-year warranty within the normal operating range of the medium.”
