Operation
Large handwheels for easy operation, also available
with gear box operation, bare shaft for actuation
purpose, motor actuators, pneumatic or hydraulic
actuators for certain services.
O.S. & Yoke
Outside Screw and Yoke is standard unit. Yoke is
limited to 10” and above for class 300, 14” and
above for class 150.
End Connections:
Flange RF ( 125 ~ 250 AARH ), RTJ
Standard packing
Our standard packing for PTFE is standard load with
cup and cone design, which still provides excellent
movement and long service life on our Gate Valve.
Stem
All wedges are provided with forged T-head, the
stem at the stem wedge connection is strengthened.
This design also allows the wedge to self-align,
eliminating the possibility of a bent stem jamming
the wedge. Our stem nut is A439-D2 coated zinc
to have better resistance on rusty, preventing rusty
by frequent operation, so as to enhance the service
life of valves as well.
Wedge
Flexible wedge is standard unit on gate valve.
Flexible wedge has a one piece, twin disc wedge
which is designed so that each half discs
independently. Solid wedge only available for API602
small forged valve ; split wedge is for our conduit
gate valve.

Globe valves are most commonly used where throttling or both throttling and shutoff are
required. which can be frequently operated due to its low friction, and can regulate the flow
easily. The lineal movement of its axis is shorter than the gate valves, therefore the operating
time and waste is reduced.
We provide handwheel, gear box operation, also work on ISO TOP Flange for actuator
purposes.
All Globe valves are full ported and meet the design requirements B16.34 for general design.
Valves are available in a complete range of body/bonnet material and trims.
There is no min. quantity on our special material Globe Valves, we also produce 1 unit with
various of super austenitic stainless steel or equivalent materials.
Standard body/bonnet materials included grade of austenitic stainless steel, Alloy 20, Super

STEEL CHECK VALVES
13/ 14
Check valves are the most commonly used to prevent flow reversal in piping systems.
Swing check valves have low pressure drops and are best suited for moderate velocity
applications. It could be installed in horizontal or vertical position. There’s the directional
mark on the valve’s body to specify the flow direction for end-users.
All Swing Check Valves are full ported and meet the design requirements B16.34 for general
design. Valves are available in a complete range of body / bonnet material and trims.
Heavy-duty design of our swing check valve would provide solid long service life in pipeline
system. We provide more ribs on the valve body, so as to make stronger tensile of valves
while the valves are operating in critical applications.
All our valves are with identical heat number which is legible on body and bonnet caps.
Excellent smooth surface of contact for disc by lapping in our own workshop, we insist on the
quality of discs and also complete swing check valves.
There is no minimum quantity on our special material Check Valves, we can also produce 1 unit
with various of super austenitic stainless steel or equivalent materials, if required.
Standard body/bonnet materials included grade of austenitic stainless steel, Alloy 20, Super
Duplex, Hastelloy C, Monel grade materials for various applications.
We are able to deliver our Stainless Steel Check Valves
within 3 days after receipt of the orders. We stock in our
warehouse from size: ½” ~ 8” in SS316 material. Website

Pressure temperature ratings are based on ANSI/ASME B16.34 (2009 edition).
The temperatures shown are that of the pressure-containing shell, which is considered to
be the same temperature as that of the fluid flowing within it.
Special consideration should be given to such items as trim, bonnet gasket material, and
packing to assure that the rating is merited in all respects.
