These valves are designed with perfect flat seating for better sealing. With a pressure rating of PN 0.2 these valves are widely used in suction side of pump to avoid flow reversal.

Rigid and sturdy design with minimum loss of head across the valvePerfectly flat seating surfaces for good sealingPreventing entry of foreign body to pump through suction pipeLong service life

Used in suction side of pump to avoid flow reversal from pump to sump with monobloc pumps

A needle valve is a type of valve having a small port and a threaded, needle-shaped plunger. It allows precise regulation of flow, although it is generally only capable of relatively low flow rates.

A name of the product DUAL PLATE CHECK VALVE self say about design construction and operation of valve. This type of check valve is simple assembly of 1) dual -double flap or can say door, 2) single piece casted heavy duty body, 3) spring and 4) stem. On the centre of body two stem holes are provided to mount / fix dual flap plate and which perform from centre as like a hinge in direction of flow with tension of spring. One stem perform as flap holes guide shaft and another as disc opening limit stop pin. Spring supports to the disc to get normal close position of valve.

Body have choice of either elastomer soft rubber seats or metal to metal seat for higher pressure and temperature application with StelliteF6 Hard face. In elastomer rubber seated check valve seat choice options are Neoprene, EPDM, NBR, Nitrile, Buna-N, Hypalon, Ebonite, Silicon, Viton etc.

Valves & Automation manufacturer and exporter of PTFE Lined Butterfly Valves for corrosion & acidic application. Our PTFE/FEP/PFA Teflon lined valves are available from 3(80NB) to 12(300NB) We also supply PTFE Lined Butterfly Valve with Quartern turn Gear Box, Motorized Electrical Actuator Operated (Single or Three Phase for modulating control as well ON/OFF application with or without manual override) or Pneumatic Spring Return Single / Double Acting Actuator Operated quarter turn valves.

These types of valve (Non Return Valves) are used to stop back flow to the upstream side of the valve. The design of Check Valve (Non Return Valve) is very simple. A hinged door is placed inside the Swing Check Valve body. With the pressure coming upstream the door is held open; when pressure increases on the downstream side, it forces the door to valve close, stopping any back flow.

Body & Cover made from high quality casting with liberal sections.The castings are precision machined for high performance of valve.Bolted Cover designBody Seat Ring & Disc machined to close Tolerances providing smooth action and accurate seating.Seat Ring sealweld to the bodyReplaceable (Renewable) type Seat Ring & Integral Seat can also available on special request.Stellited Hard Face F6 Seat Ring & Disc also supply on requirement.All the disc have double lock nut or cotter pin fixedIn built wear life for long duration of service.

Check Valves type combines a simple but robust construction with reliability. They are specially designed and developed for applications where a low pressure loss is essential. Wafer Type Swing Check Valve has short face to face dimensions and low weight allows a simple space saving installation between the companion flanges.

DELTA Valves & Automation manufacturing range all Pressure Safety Relief Valves are designed as per API 526. They also conform to ASME Section VIII. Dimensions of valves meet to API 521/521. Metal seated Safety Valves Testing is carried our as per API 527 for Set Pressure & Leakages.

A Safety Relief Valve is a mechanical, self actuating, pop design, spring loaded angle type valve, which is being used for the automatic release (on a set pressure) of a substance from a Pressure Vessel, Boiler, Overpressure of Pipeline or any Industrial System when the Pressure or Temperature exceeds required limits.

Control valves automatically regulate pressure and/or flow rate, and are available for any pressure. If different plant systems operate up to, and at pressure/temperature combinations that require Class 300 valves, sometimes (where the design permits), all control valves chosen will be Class 300 for interchange-ability. However, if none of the systems exceeds the ratings for Class 150 valves, this is not necessary.

Globe valves are normally used for control, and their ends are usually flanged for ease of maintenance. Depending on their type of supply, the disk is moved by a hydraulic, pneumatic, electrical or mechanical actuator. The valve modulates flow through movement of a valve plug in relation to the port(s) located within the valve body. The valve plug is attached to a valve stem, which, in turn, is connected to the actuator.
