VALVE ASSEMBLIES

RRP manufactures a wide range of valves and seats in both Full Open and Stem Guided designs, for various models of pumps manufactured by NATIONAL, OILWELL, GARDNER DENVER, EMSCO and others. RRP also offers individual valve parts such as springs, inserts, seats, discs, nuts etc. The valves are offered with the following options in API-4, 5, 6, 7 and 8 configurations.

STEM GUIDED VALVES

Stem Guided Valves & Cross Arm Seats (4 Web Design)
RUBBER REGENERATING & PROCESSING CO.
[+] ENLARGE
 

RRP made stem guided valves and cross arm seats are manufactured using CrMnMo/CrMnTi forging steel and features an extra wide metal to metal seal on the valve flange. The upper surface of the valves is serrated, which provides air tight seal between the valve body and insert. Furthermore, the rigid seat cross-arms provide greater strength and tighter sealing. The thick knock-off valve nut grips the insert tightly, thereby reducing flexes and air gap, which reduces the entry of foreign particles getting between valve and insert.

Stem Guided Valves & Three Arm Seats (3 Web Design)
RUBBER REGENERATING & PROCESSING CO.
[+] ENLARGE
 

RRP made stem guided valves and three arm seats are manufactured using CrMnMo/CrMnTi forging steel and allows greater fluid flow than cross arm seats. It also has an extra wide metal to metal seal on the valve flange. The upper surface of the valves is serrated, which provides air tight seal between the valve body and insert. Furthermore, the rigid seat three-arms provide greater strength and tighter sealing. The thick knock-off valve nut grips the insert tightly, thereby reducing flexes and air gap, which reduces the entry of foreign particles getting between valve and insert.

FOUR WINGED VALVES & FULL OPEN SEAT

RRP offers four winged single piece investment cast valve body using high impact load alloy steel featuring greater and uniform fluid flow through the full open seat with increased service life. The full open seat allows easier maintenance and seat pulling in fluid ends. RRP designed single piece valve eliminates snap rings, plates or keepers, and offers easy maintenance and installation by providing snap-on valve inserts. This unique combination will handle lost circulation material better than most conventional type valves and seats.

RRP Valve Covers & Gaskets are available in different polymers as per the application requirements for various models of pumps. These have been developed after years of field research and lab development, making them as one of the best in the market.

PULSATION DAMPNER & STABILISER SLEEVES
RUBBER REGENERATING & PROCESSING CO.
[+] ENLARGE
 

RRP Pulsation dampener also called Elastomeric diaphragms (bladder) is designed as a single unit to give maximum service life in comparison to the conventional bladders, which have prevulcanized sections and provide low service life. The bladders while flexing, tend to fold rather than wrinkle, thereby reducing the points of stress concentration and practically eliminating elastomeric fatigue. Also the extrusion through the bottom flange connection is prevented by molding a steel insert into the middle of the diaphragm. RRP dampeners are manufactured using a blend of hydrogenated nitrile rubber, which is suitable for water and most hydrocarbons with a continuous operating temperature range of -25 to 210F.

RRP also offers Stabilizer Sleeves which is required to eliminate possible folding and entrapment of fluids resulting in increased diaphragm life. The diaphragms are available for NATIONAL/OILWELL and other mud pumps suitable for model K-10-5000 and K-20-5000 of HYDRIL, dampeners.
