DelTech
Sizes 2 ½” to 24” ASME Class150 & Class 300
Leading the Industry with Innovation by Design
DelTech Controls is pleased to offer top-of-the-line products in pipeline flow control. The DelVal Series 44/45, 47/48 has been developed with extensive application, design and manufacturing expertise. These products are produced by employing modern manufacturing practices under a robust quality assurance system. These practices ensure consistent product quality and dependable performance. The DelVal Series 44/45, 47/48 has been designed to include state-of-the-art features that are described in this bulletin.
Features Top Flange The top flange is drilled as per EN ISO 5211 to accommodate direct mounting of a wide range of actuators.
Stem The high -strength stem is SS 316 or 17-4 ph stainless steel that provides maximum strength for high torque applications.
Body One-piece wafer body style or full lug style for dead end service. Both body styles offer bidirectional sealing as standard in conformance with full ASME class 150 and class 300 rating.
Extended Neck Extended neck allows for 2” of pipeline insulation and easy access to stem packing adjustment and actuator mounting.
Pin Pins are offset from the center of the stem which places them in compression rather than shear thus eliminating potential for failure. The pins are precision fit and wedge types which provide positive mechanical attachment of disc to stem. Disc Stop The disc stop is a machined position stop on the body that locates the disc in the seat to achieve maximum seat and seal life. The disc stop is designed to prevent disc from rotating in to the wrong direction and minimizing possible seat damage. Seat Retainer Retains seat in the body and is supplied in the same material as the body. Stem Seal Stem assembly is “live loaded” with two Bellville Spring Washers. This ensures continuous compression of packing and sealing contact at the stem and body. Rocker shaped gland bridge compensates for uneven adjustment of gland bolts.
Blow-out proof stem Retainer circlip provides blow -out proof stem.
Bearings Top and bottom bearings, consisting of a 316 stainless steel /TFE glass fabric liner bearing surface, securely support the stem. Disc The disc has been engineered to maximize flow and minimize resistance to provide a high flow coefficient (Cv). The standard disc material is 316 stainless steel. Seat The unique seat design utilizes a flexible lip seal concept. When the disc closes, this action causes a slight deflection in the seat, energizing the seat. During this energized position, the seat has a stored energy force constantly pushing against the disc. In addition to this ”energized” force, when pressure is on the insert side, the pressure pushes under the lip which further amplifies the sealing force between the disc and the seat. Bi-Directional Dead End Service All lug valves are suitable for dead-end service to pull ANSI pressure rating, bidirectionally.
Adjustable Stem Packing The stem packing system features a pull down gland with easy access to the adjusting hex head nuts without removal of the actuator.

Feature and Selection Double Offset Disc Design
Seat Pressure / Temperature
CENTER OF VALVE
800 BODY
DISC OPEN
1st Offset
DISC CLOSED SEAT
STEM
2 nd Offset
The offset disc produces a cam-like action, pulling the disc from the seat. This action reduces seat wear and eliminates seat deformation when the disc is in the open position. The disc does not contact the seat when the valve is in the open condition; therefore, seat service life is extended and torques are reduced. As the valve closes, the cam-like action converts the rotary motion of the disc to a linear type motion effectively pushing the disc onto the seat.

Metal Seat Metal Seat : Flexible metal seat offers a very high sealing capability with low leakage rates. The mechanical properties and the shape of the metal seat allows it to flex and maintain a constant positive sealing against the disc.
NACE service All valves conform to NACE MRO 103 standard. These valves are well suited for oil and gas industry applications requiring resistant materials to sulfide stress cracking. Steam

An engineered fluorocarbon polymer that is rated o for 500 F. Excellent for handling aggressive fluids at high pressures. Ultra is recommended for extended service in hostile environments involving chemical, thermal, and mechanical stress . Ultra has excellent thermal stability and is ideal for steam, hot gases, and a variety of process chemicals where service can be also be subject to pressure cycling.
Fire Safe Seat
Fire Safe Seat : During and after fire, when the resilient material has been partially or completely destroyed, the metal seat ring provides a positive seal by remaining in constant contact with the disc in either direction of media flow.
CODES AND STANDARDS General design and manufacturing :- API 609 Category B / MSS-SP-68 / EN 593 Inspection and Testing :- API 598 / MSS-SP-68 / EN 12266-1 / AISI / FCI 70-2 Fire safe testing :- API 607 / ISO 10497 / EN 12266-2 Pressure temperature rating :- ASME B 16.34 / BS EN 12516 -1
Valves are available for saturated steam at 200 psi rating for series 44 / 45 and 450 psi for series 47 / 48. Vacuum Standard valves are rated for tight shut-off of vacuum to 2 x 10 -2 torr. Oxygen Valves for critical gaseous oxygen service are specially prepared, cleaned, inspected, assembled and tested to ensure removal of all burrs, sharp edges, dirt, hydrocarbon oil or grease and other contaminants.
