Full Lug Dual Plate Check Valve
Full Lug Dual Plate Check Valves designed and manufactured strictly to International Standards API 6D, API 594, ASME B16.34 or Equivalent
Axial Flow check valves are designed and manufactured strictly to updated International Standards of API 6D, ASME B16.34 or Equivalent
Screwed 、Clamp 、Welded vavle
The American standard cast steel check valve has hard alloy welded on the guide rib by buildup welding. The guide sleeve of the upper cavity of the valve body is made of stainless steel to ensure smooth action of the valve flap; the valve flap and valve seat sealing faces are made of cobalt based hard alloy by plasma spray welding, and are thus high in hardness, erosion resistant and durable. With advanced pressure seal design and high purity graphite ring gasket, the valve is highly airtight. The middle cavity of the valve is of pressure self tightening seal structure; the higher the pressure in the cavity, the better the sealing performance is. The valve flap rotates along the pin outside of the valve seat to reduce impact at the moment of closing.
1.Face to face according to standards DIN3202-1999, K1
2.Working pressure: 1.0Mpa/1.6Mpa
3.Pressure test according to standards: API598 DIN3230 EN12266-1
4.working temperature:
NBR: 0℃～+80℃
EPDM: -10℃～+120℃
5.Medium: Fresh Water, Sea water, food stuff, all kinds of oil, air, acid, alkaline liquid etc.
6.Lever: Ductile iron, very resistant
High Performance Metal seal Butterfly Valve
The flange type multi-layer metal hard seal butterfly valv has the following features:
1. U shaped stainless steel seal ring is used; the valve plate has certain elasticity so as to have good sealing with the butterfly plate no matter at high temperature or low temperature;
2. The valve is metal on metal line sealing valve; the sealing faces of the butterfly plate is made of stainless steel or hard alloy by buildup welding, and thus have good wearing resistant performance and long service life;
3. The butterfly plate is designed to be streamline type; the parameters of the through rod and the anti-wearing sleeve provide good sealing performance and temperature, pressure, wearing and corrosion resistant performance to the valve;
4. The connection method of the valve can be designed to be flange connection and clip connection;
5. The drive method can be manual, electric or pneumatic.
Technical features and applications
1. It adopts triple offset wafer type and flange structure, with reliable seal performance. When opening the valve, Disc doesn’t touch the seal seat, so it eliminates the un-balanced load of seal seat, so as to prolong the valve’s working life. The valve is also high temperature resistance, wear resistance, and anti corrosion.
2. The valve is widely applied to the pipeline of petroleum, chemical, water treatment, high building, water supply and drainage, etc.
Lug Concentric Butterfly Valve
The Lug Concentric Butterfly Valves is designed to maintain a seal against bi-directional pressure differential to prevent back flow in systems designed for unidirectional flow. It accomplishes this with a tightly fitting seal, i.e., gasket, o-ring, precision machined, and a flat valve face on the upstream and downstream sides of the valve, valves have threaded inserts at both sides of the valve body. This allows them to be installed into a system using two sets of bolts and no nuts. The valve is installed between two flanges using a separate set of bolts for each flange. This setup permits either side of the piping system to be disconnected without disturbing the other side.

Lugged High Performance Butterfly Valve
The Lug High Performance Butterfly Valves provide accurate control of high capacity, moderate pressure drop services. The double offset design provides an approximate equal percentage flow characteristic and facilitates tight class VI shut-off, resilient-seated construction or class IV with metal seals.
The High Performance valves are available in Soft Seat (Up to 200°C depending on size and pressure), and Metal Seat (Up to 600°C) variants (fire safe on application).
Rubber Lined Butterfly Valves covering WAFER type Rubber lined Butterfly Valves, SEMI-LUG type Rubber lined Butterfly Valves, LUG type Rubber lined Butterfly Valves, FLANGE type Rubber lined Butterfly Valves
Symmetric disc design ensures favorable flow characteristics and low pressure drop Concentric shaft ensures low operating torque Lining gives a good protection to valve body, and acts as flange gasket, Shaft penetrates the valve seat, Limited choice of seating materials(Elastomer, only), Suitable for installation in Low Pressure System, Not suitable where FIRE-SAFE or FIRE-PROOF requirement apply to the valve or valve installation method.
