requirements could consult us at any time.
For metal seat, temperature range from -196℃ to 425℃. For
soft seat ball valve, temperature range from -29℃ to 200℃.
Pressure range from PN6 to PN420(150LB~2500LB).
Mostly are used in water, gas and oil. When inquiry, it is
better to offer your medium, we could suggest materials and
valves type for clients.
Yes, we have.
Ball valve, Butterfly Valve, and Plug valve are rotary
motion control valves. They just need a quarter turn to come
into action.
Standard ball valves are primarily designed for on/off
control rather than precise flow regulation. However,
certain specialized designs (e. g. , V-port ball valves) can
provide limited flow adjustment capabilities.
Simple structure, compact size, low fluid resistance;
excellent sealing performance, high-pressure resistance;
rapid opening/closing (90° rotation), ideal for frequent
operations.
Check and replace aged or damaged O-rings; regrind or
replace valve seats; ensure secure connection between the
valve stem and ball.
Ball Valve and gate valve are bi-directional valves, globe
valve, check valve and y strainer have arrow on valve body
to indicate direction.
Yes, sure. Check Valve is unidirectional valve, also called
one way valve, non-return valve. Because medium flow decide
its direction. It has swing type, lift type(piston and
ball), vertical type, butterfly type. Wafer type check valve
has three types, spring return type, single disc type and
double disc type. Anyway, could choose valve type according
to medium, pressure and temperature. Joepai Valve will give
you the best suggestions.
Gate valve is bi-directional valve, globe valve in single
way valve and has fixed direction when install. And globe
valve has better sealing than gate valve, when globe valve
close, fluid medium add pressure on disc to keep better
sealing. Gate Valve wedge is parallel with flange, when
close, both side fluid medium add pressure on wedge.
The rising stem gate valve can be seen from the appearance
whether the valve is closed or open. The lead screw can be
seen while the non-rising stem gate valve can not.
Non-rising stem gate valve handwheel will go and up when
rotate handwheel, rising stem gate valve will not. And the
rising stem gate valve requires a larger installation space
because of the stem; the height of the non-rising stem gate
valve is small, and it will not take up too much space
during installation.
Knife gate valves use blade-like knives to cut through media
containing particles or fibers. They feature a more compact
design, lower flow resistance, and are suited for
high-viscosity fluids, but their sealing surfaces are prone
to wear.
Generally speaking, for connection ends, butterfly valve has
lug type, wafer type, double flange type; for design
structure, butterfly valve has concentric type, double
eccentric type, triple eccentric type.
Stainless Steel: High corrosion resistance, ideal for harsh
environments (e. g. , coastal areas);
higher cost. Brass:
Good pressure tolerance but prone to
oxidation/dezincification in moisture; lower cost and easier
machining.
Cast iron valves: ≤16 bar; Cast steel valves: ≥25 bar.
Stainless steel or ductile iron to prevent brittle failure.
Butterfly valves: Lightweight & quick operation, but
less sealing; Gate valves: Better sealing but bulky &
slower.
Inspect seals, lubricate parts, and clear blockages every
6-12 months.
A fire booster is designed to enhance water pressure in fire
protection systems, ensuring adequate pressure and flow for
hydrants or sprinklers during emergencies. It is critical in
high-rise buildings, industrial zones, or areas with
insufficient water supply
In Australia, fire boosters must comply with local standards
like AS 2941 (Fixed Fire Pump Installations). International
certifications (e. g. , UL/FM) may be required for specific
applications to ensure reliability
Avoid extreme temperatures, moisture, or corrosive
environments. Stainless steel is recommended for coastal
areas to resist salt spray
Key parameters: max pressure (Bar), flow rate (L/min),
material (Brass/stainless steel), energy consumption, and
noise levels
Union ball valves (with union connections) are widely used
in piping systems requiring frequent disassembly or
maintenance.
Union ball valves have union connections (threaded or
flanged) at both ends, allowing quick disassembly without
cutting pipes. Ordinary ball valves are typically fixed by
welding or one-piece threading, making disassembly
difficult.
A fluorine-lined valve is a valve with a lining of
polytetrafluoroethylene (PTFE) or other fluoroplastics on
its internal surfaces (e. g. , body, ball, seals). Its
structural feature is using fluoroplastic’s corrosion
resistance to protect the metal body from corrosive media.
They are used for highly corrosive media like strong acids,
alkalis, and organic solvents
It depends on the lining material:PTFE lining:Typically
≤150°C (short-term up to 180°C). PFA lining: Higher
resistance, up to 200°C.
Exceeding these limits may cause softening or delamination.
Fully welded ball valves are permanently fixed to pipelines
by welding, offering superior sealing and pressure
resistance for critical high-pressure applications.
Advantages:Zero leakage risk with excellent sealing;High
structural strength for pressure and shock resistance;Long
lifespan and low maintenance. Disadvantages:Non-detachable;
repairs require cutting the pipeline;Professional welding
skills needed for installation.
